thx1138, thanks. Very helpful and informative. I actually did all that and then some before my son went to Nature's Classroom.
Do people really send their kids to summer camp for 4-6 weeks?! That's basically the entire summer. I'm a SAHM, and couldn't imagine sending my kids away for that long.

If they wanted to go to camp for a week, *maybe* 2, I would look into it, but certainly not for anything longer. Summer is a special time for us. We usually take a family vacation, spend a lot of time outdoors at the pool, beach, etc. and go on several day trips visiting amusement parks, museums, and so on.
