A Magic Bus near Highway 7

HIghway 7 near Christmas Lake Road.
I stopped and poked around, to see if this was the Green Bus of Wellstonian fame. It is not. Wellstone's Bus was a 2-tone oldie with a white top. This International Harvester bus is visible from Highway 7 and has always seemed like a bright neon sign for nothing in particular. Across the Highway is a sign "Explore Historic Excelsior". It is on a ligh natural wood with a very faint lettering, as if to recede into the back ground.
