We have been fortunate in that we haven't had any major issues in 5 seasons. Just getting a rig in for service has been interesting with all of the hail storms the last few years. It took a month to get mine checked out after last years big storm.
The snow will start up where we go in October and that's when we put her to bed for the season. I can't get in or out of the areas if I can't see the trails we are on. The first year we were up there we happened to turn on the weather radio and caught a forecast for a foot of snow that night. Neither of us said a thing, just started packing. We were gone a hour later.
