Quick run down on Salt Lake. It is a blast, but it is crowded. Since I live 15 minutes from strapping in on a lift, every Tom Dick and Harry is at the resorts. The backcountry is far too crowded for the limited acreage there is. The seasons run roughly from early - mid November to midish April. Snowbird will stay open much longer and offer a Spring Pass for 300 bucks. Again though, if it is during the spring and a pow day prepare for extremely long lines.
There are tons of things to do here if you enjoy outdoors. It was refreshing moving here and seeing so many people outside running or biking. People tend to either be active here or obese. There is not much in between.
