definitely annoying; and it isn't just rv'ers
I also ice fish; a lot; out on a larger lake (~250,000 acre's). I'm on a section of water about 6 miles by 9 miles without any access. I'm out there in a tracked jeep pulling a large permanent house; all setup without another person as far as the eye can see and it'd be hard to get to me. all happy and cheerful
In the late afternoon I can see a snowmobile coming across the lake; sure enough he drives within 3 feet of my door and setups up within 50 foot of me.
Seriously; the entire lake, there is only two of us and this clown sets up within an extension cord of me. He moved about 3 times around my house; re-drilling holes and the like. Prolly didn't help that every 15 minutes I'd get the wife/kid to hoot and holler about how that was the largest fish they'd ever seen "awww dad, why do we have to let it go" :) :) :)
