Quick vid of recent visit to MTH in MD… 
Pics of the B & O Museum in Bmore… 
Excellent pics, THANKS!
Darn it … I live in Maryland and have never been to the museum … that must be put on the top of my list !
Museum is well worth the trip, they have train rides out to the point were they first started the railroad, stone is in the museum. MTH is open to all, just have to call ahead and setup time.
Great pictures. Glad to see you post on the “Pot” too.
