I leave tomorrow for a 7 day ride from Calgary to Montana, Idaho, Washington and back. This will be the longest bike trip I've taken, and the first one on my 07 Vee. I was looking at the forecast for Montana and Idaho and it looks like it's going to be a hot one. My question is, what do you do to prevent butt rash and chaffing? My Vee has a stock seat and I'll be wearing Draggin cargo pants. I don't want to spoil my ride with something that could be prevented, or at least kept to a minimal. Any tips?
