In the spirit of this thread, I decided to go out and pick up the cans that had been littered all over the course in recent days. I took two bags because I feared I was going to collect 50 cans. I reached that total by the time I got to Hole 8's teepad.
I ended up collecting 74 cans in one pass through the course. And I didn't even look that hard. I'd say 90% of them were beer cans. I didn't even bother with non-can litter because I only had so many hands. I'll have to do another pass I suppose.
To top it all off, I thought I'd treat myself to a round afterwards. On the second hole, my XL gets stuck up in a tree way up high. After about five minutes of throwing things at it, it appears the disc seems lodged up there, so I decide to pick up my bag and walk to the next hole and let a group of rec players play through. Sometime in the 30 seconds I had my back turned, the disc apparently fell out of the tree, and one of that group ran up, grabbed it, and took it. I saw him running back to the teepad with a yellow disc, and I know it was mine because I stalked that whole group for an hour after that and none of them had a yellow disc. Related rant thread to come.
So, between those two things, I'm not terribly happy with disc golf humanity right now.
