I've been to COC for the last 3 years, great coaches great terrian plenty of stuff to do off the snow. I havent been to any where else so i dont know about Windells Etc. but COC is definatly worth it.
Me and my brother were just messing around last week and we found this.

All you need is a pair of shinpads, used in soccer or field hockey and put them on your feet.
hope this provides something for people with no snow yet .
