Now that I can "find my State Park with both hands", here's what the Camden Trail probably looked like.
Depart Camden northeast on AR-79 to Eagle Mills; AR-9 via Holly Springs and Princeton to Tulip; County Roads to Leola; AR-229 / AR-46 to Jenkins Ferry State Park; onward along AR-46 to Sheridan then U.S. 167 / AR - 167 toward East End; catch AR-367 just south of East End and head north via East End / Iron Springs / Parkers / Ward and follow AR-367 into Litttle Rock.
Measure twice, cut once.
