Just thought id share my idea in case any of you nuts can get away with it.
There I am fazer all attatched to the optimate waiting for ice to disapear and getting the kayak out; Heather comes out (wife) - "what you doing its way to cold to play in water"; big smile on my face "grand kids coming over at weekend, Im taking them sledging; this will be much faster than a sledge and much more fun"
Needless to say 5 minutes later kayak back in garage
