I joined the Electronic Flyers of Virginia (http://electronicflyersva.org/). A great group of folks with a nice flying field at Sherando Park, near Stephen's City, VA (a few miles south of Winchester). A few folks also fly gas aircraft as well.
I also fly my foamies at a park in Charles Town, WV.
I'm near Front Royal... I flew loads of flight sims as a kid, and has a semi-serious RC buggy (all 25 years ago), but I always wanted to get into RC. Now that I live in a rural area, I realized I have the room to fly! My radio and electrics should be arriving on a FedEx truck today, and I ordered a few speed-build kits last weekend. I ran across the Winchester/Stephens City group via google search... almost showed up to the Chili event, but I thought it would be weird to be the new guy showing up with no models, no radio, and no chili!
I live in Maryland, but there is a great field with a long runway and heli field in Gaithersburg hidden behind the swim center and archery range. They just installed a second solar powered charging station, which is great when your charging batteries while you fly. Somewhat info-lacking webpage at http://www.dc-rc.org/
