The only U.S. Cambridge I’ve been to so far is the one in Massachusetts, where I live, but plans are in place to start visiting as many namesake Cambridges as I can. Some (New York, Maine, Vermont, New Jersey, Maryland) are close enough for quick trips. Others (Idaho, Oklahoma, Missouri) will take a little more planning. Meanwhile, I’ll be relying on written interviews to gather information.
Here is what I think is the map of all the towns and cities in the U.S. named Cambridge.
