A few more Chess ideas:

We found FREE chess Club at library, This is probally a more casual club but it has been a good start for us.

There are Chess Summer Camps, search Davidson Data Base & google

Our Barnes & Noble book store has an outside Over sized Chess board, the squares are big enough to stand in. I'm not sure how common this is but might be worth looking into for Fun.

There are also some more threads here about chess.

Hope this is helpful
