Best seed selection in MD?
I moved to MD in the late summer of 2009 but I didn't garden because I lived in a tiny apartment. I just moved to a beautiful house out in the country and I'm ready to get some serious gardens going (vegetable and flower). Since I'm still kind of new to the area I was looking for suggestions on who (locally) has good seed selections? I'm in Mt. Airy (between B-more and Fredrick) but I work in Rockville and Mrs. sdrawkcab works in Beltsville just past College Park so we're all over the place on a regular basis. I remember the Behnke on Rt. 1 has a pretty decent spring seed selection but who else has a selection worth checking out?
On a related note- Is there a local seed exchange for PA/MD/DC/VA people? I know there is a whole GW forum about seed trading but it seems like there are enough 'local' people that a face-to-face seed swap could be possible.
Thanks in advance,
