I was taking my gf home for vacation from ranches today around 4:00pm. We were heading on Hwy 99 back to Sacramento. Just had to stop on Hwy to get pic of this. Don't see this many times in Earthquake country.

Yikes... that's an angry-looking cloud!
This is a situation where Monty Python had the best advice: Run away! Run away!!!!
