The Postal Museum in Washington DC has a great exhibit about the early days of mail between Boston and New York, including a simulation of the eerie ax-marked forest path which used to guide the way between the two cities. Imagine traveling along the Mass Pike route without the actual Mass Pike being there. That's a lot of forest, most of which is still there.
By the way, you'll look fruitlessly for an exhibit on the history of "going postal" at the Postal Museum. I know because I looked for one, but I didn't think it was a good idea to ask the staff did they have plans to add it.
