This is what I grew up with. "Scenic" New Hampshire. Neighboring Maine had "Vacationland." I thought I had detailed the historical differences among NH, VT, and ME tourism in a previous post, but I can't find one that includes it. I shall have to do that soon, as it is likely of interest to more than a few. From the first letter, you can tell that this plate was from Hillsborough County.
Governor Meldrim Thomson was behind that.
Great American Plates is a good resource if you want to know both current and historical plates. There may be an even better one somewhere. Browsing there, I realised I had forgotten that Alaska used to have "North To The Future," which is typical Alaska weird. The deeper you go, the more you can see how becoming an authority would take some time, like being a birdwatcher. If there are this many plates just for Montana, the sum total of all the American plates must be hard to keep in memory.
There is a danger in playing the license plate game, as people put frames around them to show their support for a college or a dealership or a joke - seldom a funny one - obscuring the state name. At this time of year, many plates are grey with grey letters also. Trying to see those while driving takes one's attention of the road. That would be hard to explain to the judge, I think. Or the insurance company.
