Redhot, an Appalachian Trail through hiker, tied his passion for hiking together with his love of maps to create Redhot Mapping. Redhot Mapping sells scratch-off maps to help track an attempt to hike all the trails in the Smokies, or to use as a progress marker as hikers complete sections of the AT. The topo lines in the pepper form represent change in elevation, as well as the mental ups and downs of a significant hike. Form is self-explanatory.
