Before seeing the porcupine in the previous post, we went out to Hanford Reach. We'd planned to go tracking there, but the wind was quite brisk - blowing sand and tumbleweeds all over the place. So instead we had a nice drive around and on the way back stopped to appreciate the storm and take this video.
My friend who lived in the south most of her life and so is more familiar with such things tells me that there is a funnel cloud behind us that shows up in the a few bits of the video. Guess we were lucky the storm didn't get even more exciting.
