I've been visiting the Upper Valley this holiday weekend... That's what they call this part of the Connecticut River Valley that joins Vermont and New Hampshire.
Anyhow, I found an old covered bridge, called the Baltimore bridge. It's on display outside of Springfield, Vt. It was moved to sit next to the Eureka schoolhouse (oldest one-room schoolhouse in the state).
Meanwhile, readers of the Baltimore Sun newspaper might recall mention of an area called Baltimore, Vt. about a year or two ago. It's not really on the map, but it's like an informal collection of dwellings (hamlet? village?) near the town of Springfield.
