Paden,
I had been "managing" the ice buildup all winter until that 4' in about 10 days. Once that hit the door and the sun started its work, we've currently got about 10-12 inches of solid ice buildup at the bottom of the sliding door. That door is a 2x6 wood frame with corrugated steel covering the frame, so any "torch work" would risk damaging the wood frame. I've got salt down to help melt it, but with temps below zero-mid teens, well, salt ain't working.... It'll get there, but it's a bit "self defeating" to have worked all winter to keep the door operational and "WHAM" .....
Oh well, with 3-4 feet of snow cover, there's great snowmobiling "anywhere and everywhere"
Lemons? Na, just too much lemonade
