Can I be the old curmudgeon and say leave the computer at home. You don't need it. I've been doing brevets for 20 years and never used one and I can count on one hand the number of times I've gotten lost. We (well at least I) spend all of my week working with confusers, I want to get away from them on the weekend. Part of the adventure is navigating your way through new territory. Anyway, I'll go back to my rocker and yelling at kids to get off my lawn now.
