I used to do quite a bit of fishing small streams in Oregon for trout and steelhead. I usually ended spending more time picking up trash than actually fishing.
I've hiked in remote areas miles from any roads and still find trash that I pick up. It's just different trash. Along the side of the road it's pizza boxes. In places like the Mt Jefferson wilderness area miles from any road it's energy bar wrappers and energy drink cans.
You're right. There are many pigs out there and they come from all social backgrounds. I'll never understand it.
Pretty bad stereotypical portrayal of a Native American but it was 1971. I remember this commercial from when I was a child. It had a lasting impact on me.
