I think it's a great thing. Yeah, you learn some of the technical skills, but you also meet various leaders (and other people with experience), and without Basic, it's hard to get on a club climb. One way to look at it is that you can spend $385 to climb Hood (with Timberline Mtn Guides) or $770(!) to climb Rainier (with RMI), and you get one summit out of the deal. Most Basic School leaders give their students a shot at Hood, and some give them a shot at Hood, St. Helens, and Adams. Don't listen to the rumors that you can't get on climbs. The year I took Basic I did St. Helens, Hood, Shasta (via the Whitney Glacier), Adams, Glacier, Fernow, and Stuart, all as Mazama climbs. I got a chance at Rainier with the Mazamas, but the rangers shut down the route when we were at Ingraham Flats. I also did Jefferson with someone I met through the class (and did quite a few mountains on my own.) I've since gone on to take other classes and started learning how to become a leader myself. I never would have dreamed of doing some of those climbs on my own that first year, and I feel the Mazamas have given me a chance to climb (and learn) from experienced people.
