Okay, so my local climbing gym seems to have a beginner's class on Monday, and you guys have pretty well convinced me to sign up.

I tend to like new experiences better when I know what to expect in advance and the guy one the phone (yeah, this is how much you guys convinced me, I actually used a phone) was sort of like, "oh anyone can do this, it'll fun, just come and see." So, what should I expect?
