I can guarantee I'll find a combine within an hours drive of the Ambasador Bridge...on the Canadian side...since you did not specify hour on the U.S. side... ;-)

Port Huron is about an hour at the prevailing traffic speeds on the I94 speedway isn't it? I always ended up with the box speedo fully wound out on that drive (stupid 85mph speedo they used back then) for the northbound trip. Theres probably some sort of Pioneer village in the area with a pull behind harvester (which was also spec'd in the original challenge as an alternative to a combine)...
