possibly the funnest thing ever invented....get a pair of old shoes that are still useable and cover the bottoms with duck tape...lots of it.make sure it sticks and stays on really well too. Then find a packed snowy hill or even an icy road will work. Just run and slide, you can go so fast its scary if you have a steep enough hill. build a jump and you can even do rails with em. if you havent tried this go out and tape your shoes and go hit some rails, funnest shit ever when theres not very much snow. i was doin it yesterday and couldnt stop and i hit a parked car on the road.
