Don't expect to find 350 Main Street and 351 Main Street across from each other. Changes in the cross-streets over the years have made the numbering less than uniform. Folks here are pretty considerate when it comes to driving, and locals expect even the quickest-paced New Yorker to fall in line with the more leisurely tempo right from the start. Might as well, you'll just get frustrated if you think you can move at warp speed here. Once you pull off the interstate, you'll instantly be aware that Park City is a hamlet, with farms and quaint older homes lining the road into the center of town.
Traffic can be slow-moving as skiers come and go, especially during midmorning and late afternoon.
Summer traffic is lighter. Relax, check out the scenery and go with the flow. Most people, once they get into the center of things, prefer to get around on foot. The sidewalks on the three major streets are quite narrow, and you'll be sharing them with lots of other pedestrians. If you like to amble along at a slow pace, it's a good idea to move to your right so others can pass.
