Did a nice 110 mile loop today following the newly purchased DeLorme PN-40. The GPS and mapping did fine 95% of the time, but a few times I followed it blindly down imaginary lines through the prairie, and other times on roads that were nothing more than single track cow trails. Most of the riding was rocky ATV track, rocky roads, and a short bit of fast gravel roads.
This was the route
with some variants for back tracking in the Bermuda Rectangle of the prairie with many roads leading to dead ends at high power fences.
