I noticed that the temps projected for Valley Center and Lake Henshaw are in the low 80's for this weekend. One might speculate that the temps on the 30th should be tolerable for more than just an early morning straight run up Palomar.
This would be a repeat of the ride Jeff organized in June. Rincon to Mt Palomar to Santa Ysaebel for pie via Mesa Grande, with a return either via Mesa Grande or Hwy 79. I think the full Pie Ride should wait for even cooler temps.
