Wow, continued thanks for the wealth of information and advice.
There is little to no bike infrastructure and support through most of Ga. The state bike route isn't marked anywhere aside from Google, State Parks don't offer "biker" sites to my knowledge. Even the primitive sites are pretty high here, $15-20 IIRC and maybe more now, I would have to check. I have never seen a hostel, not to say that they don't exist as I really have never looked. The area I live now is pretty rural so I can't see there being a lot of need for them. I think the trick to stays around here would be to research and find the seedy cheapies for motels, which are pretty common to the whole region, that you can live with.
I already have a "pre tour" test set up for myself in planning. I intended to do it this fall but life got in the way. If the weather will do as it has the last couple of years I should be able to complete it this winter. I intend on hitting a couple of the state parks in the area as day trips, perhaps camp at one or all of them and worst case two of the three are very near family or friend's houses. I am already putting on the mileage that I intend to do, and just need to work on loading my trike a bit to test riding like that.
