We used to be, although we're not there anymore.
The Fairfax County Fire Department did a lot of safety checks at the Babies R Us in Chantilly - at least they did when my DH managed there. Depending on where you are in Fairfax, that's a bit of a drive, lol, but you could try calling over there and asking for the name/# of the person who BRU liasons with to do those seat checks and getting in touch with her. (I don't remember her name off the top of my head or I'd just PM you, lol). I know they do seat checks in other parts of the county also - usually through the police or fire stations, so you could also try calling your local fire station and asking. There are a decent number of police officers in Fairfax County who are certified (although I'm not exactly sure through who or what - I think Safekids).
Anyway, I have no idea how much help that is, but hopefully it helps a little bit.
