sue, i havent registered for the tumacacori because i'm still deciding. DH is going to go out to visit my parents that weekend (i want to go but i cant get saturday off and it's just too much of a drive to go for just 2 days) so i wasnt sure if i wanted to ride it without him. if i do i'll probably want to do the 64 miles, so lemme do some research and check it out. i'll let you know.
