In reply to apulmatt:
I went to the US with Camp America in 2002, although I didn't end up working at a traditional US Summer Camp. Spent the following 3 years working there from April until November (Lifeguarding and outdoor education stuff mostly) but arranged seperately.
I know from a camp perspective Camp America are the most expensive to hire from, but we always ended up using them as the choice of people from BUNAC or CCUSA wasn't as good. Whether this was because they were better at marketing their counsellors or just had more I don't know. I do know that if you'd applied by a certain date they guaranteed you a placement, not sure if the others do this.
I loved it, was great working with so many international people, I'd still be there if I could.
I got this message from an old Camp Director last week
"Let me know if you're interested in a great job this summer. Staff facilitate five to six trips over the summer. Start out with an on site program, a trip to Yosemite, trip white water rafting, kayaking and surfing, another trip to Yosemite, and a surfing trip. It's really an amazing job."
I'd be so tempted if I wasn't settled into real life
