You're in California and Yellowstone is only five hours from you, Jerry? Just how fast do you drive?
I was in Yellowstone last year at the beginning of September and it was amazing. I recommend everyone go but then again, I'm a science nerd so I like all this geological stuff. I'm headed to the Grand Canyon, Sedona, AZ, and the Hoover Dam this year in a few weeks. I'm stoked about taking the tour of the dam.
