Scratch-and-sniffing leads me to conclude that an animal urinated on my tent. Acrid stuff! I think this happened while I was at Butcher Knife Canyon a couple of days ago. I clean it off.
I slept OK last night despite being woken up a couple of times by the crying baby and its upset parents over in the nearby tent cabin. It was a bit chilly overnight and I wore my sweater and blue jeans inside my sleeping.
The dirt-biker tour group was up early and left at 8h30 for their day ride. I managed to get a little more sleep after they left.
