Mystery Signs

Have you noticed these signs all over the upper end of the county? They're everywhere and no one seems to know what they are.

My guess is they're bicycle related. Just what we need, more organized bicycle riders on Loudon County roads. That may be unfair, may not have anything to do with bicycles.

Anybody know for sure what the signs are for? Inquiring minds want to know.
