Some good ideas here. Thanks.
The Johnny Ray will only go through one town of any size (Lafayette, AL) before returning to Opelika. No other route markings are along these roads. I've ridden the route three times recently.
I'm thinking paint instead of chalk with a distinct mark. Thanks for the ideas.
Someone at our meeting last week said we have to inform the Alabama DOT. If we don't they could "shut us down." That got my attention.
