Trapping off snowmachine

[Mikekmr]

Next trapping season (provided global warming doesnt have us running around in cutoffs next November) i will be trapping in the Rocky Mountians in southern Wyoming---i anticiapate useing both 4 wheeler and later a good snowmobile made for deep powder snow on the trapline-am figuring on worse case sceanario up there. I tried this same valley back in 1981, ignorance,deep snow and extreme temps along with general unprepardness caused my failure.---
---Do any Michigan trappers use a snowmachine for longlining? id like to know if there are any books with pics or a video by someone that does this style of trapping. This time i want to be prepared.
thanks in advance
