Pictures? Bring a kid! Sounds like you have one or more of those!
These folks have been power-pointed to death. Pass around polaroids, crafts past campers have made, scrapbooks. If the kid functions well enough, have a simple interview about what he/she likes or dislikes and is looking forward to. If he/she doesn't speak much, have a parent talk about what it means to have a place like this for their child.
That cuts the time you need for any old hillbilly shtick to just a couple minutes. Chances are the only other A/V you may want are a pie-chart of income, one of expenses, and some graphic of numbers served by category (age, level of disability, etc..).
Bringing a kid would be the number 1 choice but they are having the meeting at a time when I would have to pull a kid out of school about 30 minutes early. I just don't know if I can bring myself to do that. My piece is supposed to be mostly about club level stuff but I feel like I have to talk about the Camp CANOE for a bit. It looks like I need to just get to off my lazy butt and get to Walgreens at the very least. I really appreciate all the input guys.
