Good stories!
I had a couple, I'll try to be brief...
A few years ago, taking the family on a Northern Cascades vacation, car camping in the back of my F150.
To understand, I had built a sleeping platform in the back which left about 18" of space between the platform and the roof of the canopy. For the comfort of the family, we inflated a queen-size air mattress on the platform which took up about 6" making it feel like a coffin. I have somehow developed claustrophobia later in life and this just wasn't working for me. Around midnight, I squeezed out the back of the canopy with my sleeping bag and pillow and converted the picnic table to my sleeping platform. Some hours later, I was awakened to the sound of yapping and squeeling, pretty sure it was a pack of yotes running by, not 50 yards away. This was at the campground near 49 Degrees North, known wolf country. I had proper equipment and never felt threatened, I thought it was cool.
Another was in the campground a the West Fork of the Madison River. A cow moose came running through the campground and back again...Wild eyes, panicked. That was kind of scary.
