It's unfortunate, but all too many people don't start thinking about climbing until the good summer weather arrives. Almost all the climbing courses start in the early spring or even winter, so they can get all the lectures and field trips out of the way in time for the students to go do their experience climbs in the summer.
Kiwi, what I would do if I were you is hang out with some cc.com folks and learn some rock climbing skills this summer. Maybe join JGowans on his Adams slog this weekend, then sign up for some alpine course for the 2004 season.
