I admit I was already mostly awake at 4:50 when the noise came. I was struggling with the leave the tent to pee / ignore and hope I go back to sleep decision.
Then I heard something through my earplugs. Had those damn kids at the nearby campsite woken up early and resumed their "screaming game" from 10:30 the previous night?
I pulled out one plug. This was not a human noise. It was a chorus of animals. Bass, baritone, and tenor. One note steady, another rising and fading, one voice warbled with vibretto. It was loud; it was close but not in a specific direction. Though I've never heard them before I'm pretty certain this was wolves claiming dominion. I cede it to them. Though sunrise is around 5:05, I don't exit the tent to pee till after 6am.
Maybe it's time to get a dedicated bottle to bring in the tent. .... or make a bunch more money and stay inside all the time.
