Oh, not too bad.... mid to high 70's during the day... just enough wind to keep it balmy/comfortable -- mesh jacket weather, perf gloves. Usually, little humidity that time of the year. Everything already bloomed, lush mountains, usually no rain, and when it does, it typically waits till the afternoon, for a 15-minute popcorn storm downpour to cool things off, and wash away the dust. Then it clears up, as if it never rained.
Mountain roads are in great shape, ribs and barbeque the best in the country (I know I'm gonna hear about *that* one...)
And, usually no zombies...
