Speaking of historic buildings in Rockville, I just found this great collection of photos of historic Rockville at the Peerless Rockville website. Many thanks to the folks there for making these photos available for everyone to see.

A fascinating list of historic places in Rockville with photos and descriptions (saving the Dawson Farm residence, travelling on the trolley line from Rockville to Georgetown in the 20's and 30's, the significance of Frieda's Cottage) can also be found at the site.
