Thanks for the invite! I'll let you know when I'm in Frederick again, which is likely to be next weekend.
I'm not, but I only recently discovered that there was a field/club within the SFRA! I've been living here for about 2 years now, but only recently got back into RC after a several year hiatus. I did drive out to the field once back in March or April, but the gate was closed, and no one seemed to be here.
Not to derail this thread, but is NVRC pretty much the only legal place to fly an RC plane in the SFRA? I wish I could get some flights in at lunchtime at work in Manassas, but even that is within the boundaries!
