...I will be in Baltimore again this weekend (Inner Harbor type stuff, and the Comics Convention), but the last trip there I focused on the B&O Railroad Museum.
Enjoyed it!
It's a bit tentative, but I've learned that about two hours up the road from me in Strasburg (or is it Strausburg? a couple of miles from Lancaster), PA is their excellent railroad museum. Columbus Day weekend I may go that way to see some farms and autumn foilage, as well as the PA Railroad Museum.
Just a thought, but perhaps one day in the future, during the fall this area could be a group shoot?
