I never got to go away to camp, unless you count day camp. I wasn't really sure if it was the money or if my parents just couldn't bear to part with me.
Memory: 13 years old, YMCA day camp, really cute instructor named Brian (I still remember). That week I developed a deep interest in BB gun target practice.

Totally yummy.
The past 2 years my 13 year old daughter has gone for a week at GS camp, loved it, but finds it a little boring. This year she's eligible for a whole new tier of options, including travel to WV, so we'll see what happens.
Last summer my 11 year old son went for a week at Boy Scout camp, which was a little different because he was with his troop and not a bunch of strangers. He had a great time.
I think they'd both be happy to go to the YMCA camp though. I just can't afford all of it. It'd have to be one or the other. Day camps are fun, though, either through scouts or the Y.
