It sounds like brevets really stress you out. Hee hee. They are a bit stressful though what with the long distances, time limits, controls, and the card and all.
I haven’t had any bad brevet dreams, but I did have a pre-brevet freakout once. 2 years ago my wife and I stayed at a motel about 10 minutes from the start of a brevet in Middletown, VA. We drove together to the start then she was going to use the car for hiking and shopping during the day. When we arrived at the start I realized I left my 3 water bottles in the motel. Damnit! She, dutifully drove back to the motel to pick them up and bring them back. I got started about 15 minutes late, but overall it was a very good ride.
Are you doing the last one this year?
