Gary,
Welcome. I'm also in Northern, VA (Reston). I picked up an already built/owned WCM Ultralite last year. I figured it would probably take me several years to try and build one. So far it's been a lot of fun. I'm looking forward to the '08 auto-x season as I've been thinking of what new parts to through at the car -- tires/wheels, springs, etc.
I'm always up for a local drive/get together somewhere once it gets a little warmer. Looking forward to seeing your Stalker.
