While gathering data for a future hike of the Pinhoti, I created an on-line map and a Garmin friendly map overlay of the track.
This is only the track data needed for a Pinhoti thru and no nearby/related/connecting tracks. http://lifeat2mph.com/pinhoti/
That data mostly reflects trip-data from Solo's work (old & recent) and includes both the Alabama and Georgia sections.
Georgia's updated track/information is from Marty Dominy's GPT Trail Guide.
If planning to hike a bit further, a work-in-progress-map of the Benton MacKaye trail is at http://lifeat2mph.com/bmt/
That BMT track/data is from Sgt Rock's BMT Guidebook.
If planning a kayak trip down Alabama's Scenic River Trail, http://lifeat2mph.com/ASRT/
This track/data is my work.
If planning an even longer kayak trip; say, a 1515-mile circumnavigation of Florida, then... http://lifeat2mph.com/gm/fct/
This track/data is from my work and Florida's Office of Greenway & Trails dep.state.fl.us
