I went to the Michigan Gas show on May 11th and I had a good time. Most of the items for sale there were a little out of my reach, including a circa 1969 RC Cola thermometer, but I did buy five vintage oil company maps at one dollar each. But I did get more than that three days later when Dave Rowilson (last name correct?) who sent me lots of old maps from Shell, Texaco, Standard/Amoco, Sinclair, and many more.
