Maybe a little too late for people to make plans, but figured I would share.
There is a classic car show at the USMC museum outside Quantico. Free to register, limited space. I registered as part of ZR-1 Net Registry.
Weather doesn't look promising, but if its decent enough I will be attending. Show runs 11-3, check in 930-1030.
The museum itself is free, and is pretty awesome if you haven't been there before.
Register
here. Registration ends 5pm on 10/12.
Again, sorry about the lateness. I just found it myself.
