I threw a red disc into a tree today at Prarie Center on #4. As I began looking for it, I could see a yellow disc next to the red one. So I climbed up and shook them out. Then I noticed that neither of those was the one that I threw! So back into the tree I went and finally found mine.
Anyway, the discs have names and phone #'s so I've contacted their owners and hopefully they'll be reunited soon.
