I stumbled across this abandoned oil station after walking through a much less interesting abandoned lot along U.S. 52 in Lafayette, IN. I visited this in 2007 and unless Google is lying to me, it is still there in 2008. It appears to have been abandoned for at least several years, or at least in a horrible state of disrepair. Also thanks to Google, it appears that Leffert oil has moved up the road.
Anyway, this facility is located next to a now-unused section of railroad track which presumably used to deliver oil to it. It isn't incredibly exciting, but I enjoyed looking at it.
