On Sat the 18th of July about 1pm CDT, we were on our way to Traverse City, MI. in our 182. About midway on our 2nd leg, from Valentine, NE to Stevens Point, WI (just north of OSH), we passed two planes in trail with bushwheels, (maybe supercubs???) on the way to OSH I'm sure. Tried a few frequencies, but no luck, so wagged wings and flew on. Our 182 is Maroon on White with 8.50 main tires. Was it someone from this forum?
