20+ feet is seasonal. If you think its far fetched look it up. But to get through the 3-5 feet of ground snow you take your snowshoe and dig at the base until you hit the root flare. Cut/limb/top then drive the skidder on the roads that you previously froze in, and haul them out.
Anywho I'm starting to remember why I avoid this forum... Too many 22 year old kids who think they have seen and know it all...
Avoide it then, sounds like your gettin mad though. You may have it different where you get 20 feet of snow. You get 6 inches of snow overtop of all kinds of laps & you are gonna be one slip slidin dude. I looked at some topos if MI, you have less than 1000 feet to work on so I guess your idea of a mountain is about like the Floridians. . .
As far as I know, I am the only 22 year old here, & i know i havent seen it all & dont know it all, but I can smell horse manure. I think i could show your 548 places where it would have some issues if the snow started falling. . . . . . . . .
