I would guess that what some people would call strange may appear normal to someone that has encountered it before.
I thought it was strange the first time I watched a deer swim a mile wide body of water. It didn't seem so strange seeing it happen again a couple of times after.
We had a Whippoorwill land with in 50 feet of the tent one night, and started its, very loud, call. That was the first Whippoorwill, I think, I've heard in these parts.
I had a couple of racoons climb a tree where I had one of my hammock straps tied to. What was strange about that, I was in the hammock at the time. Probably snoring, like I normally do so I'm told, and I bet my toes were within a couple of feet of the furry critters. I wonder what they were thinking. "OMG this guys feet really stink! Don't these hairless," well I guess I do have some hairy toe nuckles, "Don't these stinking humans ever groom themselves?" Maybe that's what they were saying to each other? I don't know.
I've seen a turkey, almost, fly into my buddies head when we were moving across the water in a power boat.
It is amazing to see things that you haven't seen before or seldom see at all. Everything is, almost, explainable except I guess human nature. We are the ones that don't make sense.
It's been 8 months since I've been camping. I'm chomping at the bit to get out there, and see some "strange" things.
