I'm researching camp sites and where I wanna stay and re-up on food and all that. I'll start a thread when I have more figured out.
When you download the GPX file from the following link to the advrider page into Garmin BaseCamp it gives an extensive list of fuel, camping, eating and other stops of interest along the Oklahoma Adventure Trail. You probably have already seen that but if not it is a great planning tool.
