When we got home, I let them sit and watch tv for a while and I got dinner ready. After dinner, they went back out and rode bikes around the "safe" part of my street (ie: the cul de sac road which is across the street from me). Then it was baths and bed with lights out at 9:30.
Today I may try taking them out to Suwanee for a while. There's an indoor rock climbing place that might be good to check out.
