Yeah, I got rained on while camping. Again. But a very light rain that mostly came down while asleep Monday night. As can be seen in this #PhotoMonday image I didn't suffer much during the few afternoon showers.

Similar to an image I posted a few years ago. This one was taken while camping at the Texas Springs campground in Death Valley. I was talking with another rider when sunset exploded around us. We stopped talking and started snapping.
