Back during my senior year of high school in 2002, my Japanese teacher told us about this program. You teach english at multiple camps during the summer. There was a trip offered in the spring and it was only a 2 week trip so I thought I:d try it, and it cost about $800.
I really Enjoyed it and found out that I could come back again for the summer trip, so I applied and was accepted and got to return last summer for free, and this summer as well!
