That is water just coursing off my tent fly. I have not felt the tiniest drop yet, so I am very impressed with my MSR Hubba Hubba tent.
I heard the first thunder from a ways off as I was getting things organized to pack. I checked at the campground ranger station and, yes, severe storms were in the area and were expected to continue for the remainder of the afternoon. I decided to stay over another night and resume my ride tomorrow morning.
So the rain is now coming down in sheets. Thunder is booming. Lightning is crackling. And I’m warm and dry, and getting rested up a bit. Sounds like a win to me.
