LOL indeed scary thoughts isnt it,,, i been going to sweden for a fair few years now during winter time for snowboarding etc,, but while there we have thrashed cars around on frozen lakes along with ski mobiles etc etc.. best of all is heading out on to the lakes of a night and just listening to the noises the lakes make as the layers of water freeze beneath the ice!
best way to discribe it is.. battle scene from startwars lol..
