The children's organzier for the Mensa group is also involved in, I think, Seminole County schools (just north of Orlando). She did a great job on the children's program for the SENG conference last weekend.
I am in the northeast Florida area and am learning my way around some of the enrichment resources available in this area. There is a Saturday program during the school year associated with Stetson University in DeLand called Hatterdays - they also have some weeklong summer programs (day, not residential) at several locations throughout the state. We have started to make some contacts there, although it is something of a haul for us. The Gainesville area may also have something, but we haven't dug too deeply there yet.
