I went to JT and Yosemite in May/June. JT is truly incredible and often underrated.
Sail Away (5.8) beautiful hand size splitter, 9/10 would climb again.
Also, if you are considering Red Rocks or Josh then look at weather and climate for when you go, it easily gets too hot to climb.
If you like your beers, I highly recommend going to the Mammoth Lakes Brewing Co. if you head that way from Bishop. Its also very beautiful between those two places!
Have an awesome trip! CA is awesome!
