Well there is always plenty of good ski places to go ski or snowboard. There is also Anetelope Island which is an island out in the Great Salt Lake that you can get to from Antelope Drive in the Layton area. It is actually a state park and they have buffalo heards. You can also check out the Clark Planetarium and the Gateway Mall in Salt Lake City. The Gateway is one of those fancy new outdoors type malls. If you head south past Salt Lake and toward Orem there is Thanksgiving point which has an Imax theater and one of the coolest dinousaur museums ever. Also if you are into game shopping check out FatFin.com and look up some locations to go check out some Graywhale Media stores which are pretty cool for new and retro games. Speaking of retrogames if you have time you absolutely must go to Logan (about an hour north of Ogden) where you need to go to the Cache Valley Mall and check out Fun Unlimited which is without a doubt the coolest video game store and arcade in Utah. A huge store with wall to wall games from EVERY system ever released. A little pricey but they got everything there.
Thanks for the info, I might have to look up that Fun Unlimited and make a run up there.
