P-38! I stumbled into this place several years ago. It sits just off the highway on the middle of very rural MN. Saw the top half of a P-51 prop sticking up above the horizon and had to stop The guy behind it got in on the ground floor of building ethanol plants.

Mr Fagan was sitting in the cockpit of the P40K fuselage undergoing nut and bolt restoration talking to another guy when I knocked on the shop's door and asked to look around. I'm a nobody to him and it was Sunday. He was very tolerant of me and the place appears to have only gotten more remarkable!
