Oh no, if we had turned around and gone back to Lunsford Corner I think we would have died - at least I would have.
What happened was, after we got the last OT cache I was literally spent due to the heat and humidity. I had only a liter and a quarter which I was splitting with my lab so I was running low - down to my last 250 mL. Did we mention how hot is was?!
So we decided just to hike the last bit out, passing up the remaining caches and get back to my Jeep which we had staged at the "Head of the Trail" cache (actually on the side road just above the trail head) on 113 crossing. Truth be known, I was getting a little light headed - thank goodness for the Jeeps AC unit and the extra water stashed in the back!
Even so, it was a great day of caching! I'll have to go back this week and catch the ones I missed on the west side.
