Hi all, When it comes to climbing, I'm as green as it comes. I grew up here in the PNW (Portland area), and always had an interest in climbing, but unfortunately, my family didn't really have an interest in climbing. I ended up moving away from the PNW when I was 11 (just moved back after 14 years away), so I didn't really have an opportunity to climb growing up. I'm 25 now, and see no reason not to get started. I'm kind of confused as to where I should begin. I've been looking into some classes/mountaineering courses, etc. I know that some sort of fundamental training will be necessary, but I'd love some guidance as where I should start and what kind of equipment I should buy. Cheers
