INPUT ARTICLE: Article: Dinner out at a restaurant is a classic Valentine's tradition However, you may find most restaurants overbooked or overpriced for that very reason. If you want to take him out to eat, make reservations as far in advance as you can. Plan to eat at home, or pack a romantic picnic if the weather permits. Hire a professional chef or a talented single friend to cook the two of you a romantic dinner at home. If one of you works on Valentine's day, consider meeting up for a brief lunch. It will be too rushed to constitute the main event of your day, but it is a romantic gesture. Breakfast in bed is another classic romantic gesture. If your partner doesn't like eating in bed, just popping out of bed before him and having it ready by the time he gets up is a kind act. If your husband really loves cooking, give him the gift of appreciation. Tell him you're dying to eat a home-cooked meal, maybe make a special request for something you think he could make, then sit back and watch him cook. Cooking together can also be romantic. If you guys can stand a little cheese, buy matching aprons. If you're feeling foxy, consider cooking in only aprons. Timing is everything. If you are planning a heavy meal at home or at a restaurant, eat late. Get your romantic time together before you head out, as you may be too full and sleepy after a large meal to enjoy one another's company afterward. If you and your partner drink alcohol, drink something nicer than usual on this occasion. Get a bottle of nice wine, or buy a growler from a local beer distributor. Buy ingredients to replicate a kind of cocktail you both enjoy, and mix it up as a surprise. Design a new cocktail. If you're crafty, make a custom cocktail using flavors your husband enjoys. If you plan a week ahead, you can make a custom liqueur for the special drink. Give your cocktail a personalized name, or tell him it's an aphrodisiac. Beer doesn't have to feel casual or inelegant. Opt for a locally brewed beer with a high alcohol content, and serve it in champagne flutes or wine glasses. Red wine is a classic romantic drink for a reason. All alcohol could be considered an aphrodisiac, but red wine is even more so. Valentine's Day doesn't have to be all dinner and swooning. If you and your husband are outdoorsy, consider taking a hike, hitting a rock-climbing gym, or taking an excursion on a boat. If you enjoy dancing together, go dancing. Sign up for a one-off class and learn a new kind of couple's dance. If you're already expert ballroom dancers, consider a romantic team activity, like AcroYoga or a couples-oriented contact improv class. Hike somewhere gorgeous and have a picnic. If your February's snowy, go ice skating or sledding together, or take a trip to a ski lodge. Being in a new place will make your special day all the more special. Book a weekend trip to a nearby town, or find a cheap flight to a totally foreign place. Make the journey part of the celebration. Pack media you can enjoy together, and make pit stops in interesting places. Consider taking a long train ride together instead of flying or driving. You can watch romantic movies with headphones in and eat a delicious meal that you pack. Sleep in a hotel. Even if you can't afford a trip out of town, consider booking a room in a hotel for the night. Staying in your town doesn't mean you have to follow your ordinary routine. Take a trip to an activity you can enjoy together. Book a day visit to a spa, or camp at some natural hot springs.

SUMMARY: Eat. Drink like royalty. Get active. Travel.

INPUT ARTICLE: Article: Tunnel boring machines, called TBMs for short or "moles," feature circular plates on the front called shields. Disc-shaped cutters on the shield tear through rock and dirt, which passes through openings in the shield onto a conveyor belt inside the TBM that deposit it behind the machine. The types of TBM shields vary according to whether the mole is to dig into soft, wet ground or hard rock. Shield diameters range from Aker Wirth's 26.3-foot (8.03 m) shield on its TBM used for Switzerland's Linth-Limmern power stations to Hitachi Zosen's "Big Bertha," with its diameter of 57.5 feet (17.5 m). Moles designed to dig tunnels below the water table also feature chambers at the front to pressurize the ground being dug through. For large jobs, multiple TBMs may be called for. The Channel Tunnel required 11. For a surface level tunnel, this is no problem. If the tunnel is to be bored deep underground, an access shaft, usually circular, is drilled and lined with concrete. The TBM is lowered into it, and the tunnel is excavated from that point. For long tunnels, multiple access shafts are drilled. When the tunnel is finished, the access shafts may become ventilation shafts and/or emergency exits. If they are not so employed, they are left in place for the life of the tunnel. Segments of pre-cast concrete are erected behind the TBM to form a ring at pre-determined intervals. The sprayed concrete, or shotcrete, coats and stabilizes the tunnel walls. The shotcrete may include steel or polypropylene fibers to strengthen it, much the way steel rebar is used to strengthen cast concrete. The shotcrete also contains an accelerant to help it stick to the tunnel walls and dry quickly.

SUMMARY: Choose the right tunneling machine for the job. Get the machine into position. Erect tunnel supports as the machine bores through. Spray concrete on the excavated walls between the support rings.

INPUT ARTICLE: Article: Unless you receive enough rainfall for a storage system, using a hose to water your garden will be most space-effective. Check for a faucet or water line on the roof, and attach your hose. If you can find neither, use a watering can. The most reliable watering method involves setting up an automatic irrigation system. Refer to your garden map as you decide where to place containers. The ideal pots will be lightweight and deep enough to accommodate your plants' roots. Choose wooden or plastic containers over heavier materials, like terracotta. Depending on your preference, you can raise your plants from seeds or transplant young plants from nurseries. Seedlings are usually stronger and pest-resistant, while seeds are much cheaper. Seedlings will fare better than seeds in cooler or windier climates. If desired, you can also start the seeds inside and transplant them later as seedlings. Windbreakers will keep your plants from drying out or getting damaged in harsh weather. Trellises are the most common option for rooftop gardens because they have holes, as solid windbreaks will knock over easily. Build or buy a trellis, and place it where it will block the wind's direction. Decorate your trellis with crawling ivy, sweet peas, climbing roses, or morning glory.

SUMMARY:
Connect a hose that leads up to your rooftop. Add containers for your plants. Place your seeds or seedlings in the containers. Install a trellis.
