What, the state fair doesn't seem like a prize target to you? What about the Wegmans in Hunt Valley? That place is packed on the weekends.

I live in Lutherville.
With the crowds the Fair has been drawing the last few years, I wouldn't consider it too big a target.
Wegmans, on the other hand, does draw a big crowd, but it's so far out in the hinterlands of the area that I doubt any Ter'rist will ever hear about it.
