Here comes my try at the COTM. I'm light on petroliana, but heavy on history.
I became interested in Pure in the mid-1970s, when I took my freshman English class in the old Pure research building. This was the first campus of McHenry County College. Before the Union takeover, there had also been a small gas station on the grounds, on U.S. 14 in Crystal Lake, Illinois, which was the first station to get makeovers accounding to the whims of the powers that be.
So, I probably have seen every Pure station style there ever was, when I include the tiny cottage stations in northern Wisconsin. I had hoped to get up there last month to take pictures of what remains, but was unable to do so. I'm sure the rest can be filled in by you!
