When we reached FR139C along the ridge top, Lloyd and Michael hiked 1.3 miles to the north end of the road where we had left his car at our originally planned canyon exit point. I sat here against a tree waiting for them to get the car for the drive back to camp. The top of this ridge has mostly ponderosa pine trees except for the occasional oak tree and cluster of Aspen. It was a pleasant resting place until some bug crawled up under my pant leg and bit me in the thigh. It felt like a bee sting, and I quickly smashed it and shook out my pant leg without ever seeing the pest. Two mornings later I discovered a track of small red splotches along my thigh that itched like crazy. Perhaps it was Arizona's version of the fire ant that had so viciously attacked me.
