If you're doing a road trip, call ahead as the hours on the site aren't right (closed Sundays, I believe).
The vinyl does need to be organized a lot better and they are looking for CDs to take in on trade.
Nothing in the way of stereo gear or instruments looked very appealing to me but there is a guitar store right across the street.
The guy who owns the guitar store is a really nice guy, too, but I'm a Gibson man so that means Guitar Trader down in Towson, MD.
