I will try to make it over sometimes; may try to get some neighborhood kids to come, too (10-12 yr olds) so if anyone else wants to bring the whole family, let me know. It is always an easier sell if other kids will be there.
Also, I stumbled across the fact that Revolution Cycles has a Thursday night MTB ride; according to the guy I talked to, they get up to 15 riders and go to different spots every week; might be worth talking to someone there.
