I confined my acquisition of these to a few states in a geographic area. I never had
any thought of collecting all of them, and many, many were produced for areas in
which I had no interest. This confined me to only a few, luckily. There were temptations, such as when I visited a brewery museum in Wisconsin (searching for
cars not done in my favored area) and became slightly intrigued with Wisconsin
breweries, of which there were a lot. I repressed myself from going off on that tangent. However, if more are (or have been) done for my area, I want to know
about it.
