MapQuest continues to be one of my favorite sites, one I use often, and one which really impresses people. As the site name implies, you can get maps. You type in an address, and see a map which shows the location.
People flip over it.
I used it just last week for my mini-vacation. We had 5 people driving from a common site in Milpitas to a house in Sacramento. TripQuest allowed me to give everyone clear directions. You enter a starting address and an ending address. TripQuest provides you with a map showing the overall trip and local maps for the starting and ending addresses.
