I applied in-person. The process took 2 months. I interviewed at Camp Kennybrook in Oct 2012
Interview
Basically the head counselor selected me and we spoke over the phone. I also spoke with the owners, it helped that they knew me before hand too. It was relatively easy and the head counselor was easy to talk to because she was in the same position you are. I heard from them after about a month of back and forth.
