The SMs are brutal HOT! From May on I never ride there unless I can get a start with first light, and off the road by 11. And except for the Rock store and the store just a piece down the road from the Rock Store, there are NO places to buy water. I know the locals know places where they can get water - not info I have... so I always carry 3 24 oz bottles, 2 water , 1 with diluted electrolyte.
Amazed that you carried as far as you did !!! I woulda been vulture snack long before that !
And when it's HOT in the SMs, there often is no breeze to help evaporative cooling...
You did well to take the ride - to ride another day !
Ride On
