I commend you for hiking in this heat Rain Man! We hiked up to the top of Flint Mill Gap last weekend where it's cooler but on the way it was a hot & grueling climb. The relief of the Spring in a fern strewn Oasis at the top was worth it!
Wish I was back there but it's raining this morning and it's a welcomed relief since my A/C is out and the back yard has been my refuge.
So I'm feeling your pain & gratitude of the trail.
Keep us informed of your progress!
