Disc Golf Discs Appear on Streets in South Austin

This is the second time in about ten years that I've seen and recovered a disc from the streets of South Austin. I have pictured in my head how they ended up there. Perhaps someone left it on the roof and it flew off. Or they were  back biking back home and it fell out of there backpack. My favorite idea is that young people are chucking them out of their car and seeing how they fly and how fast and how its different from throwing on your legs. Its a new sport in the works.
