I think the bigger issue is fuel costs for tow vehicles. Our diesel vs. sled gas costs aren't even close. High diesel prices mean two things for me (living in Minnesota and riding out west): 1. Fewer trips 2. More people per trip.

Fewer trips but maybe longer more enjoyable trips because the more riding and less driving is worth something right there? I would much rather go for a full week, then to take two short trips of only 3-4 days each. It's just too much truck time and not enough ride time. Sure you may get into a sucky time for snow or temperature but for us midwest guys it would have to really suck for it to not be good for the most of us.
