In the late 90s, there were billboards all along Needmore Road in Dayton, going to the Hamvention. I thought they were amusing at the time, but that's all there was - no real information about what they were or what they did. I assumed they were some local search thing or perhaps an early attempt at specialty product delivery. Doesn't seem to be any real information out there, I suspect they didn't last long enough past the wild west to make it into archives. Just a curiosity thing for me mostly.
