Watch out for flying frisbees! Being aware of your surroundings is always a good idea while looking for caches, more so when others might be throwing hard plastic disks around. On the other hand, I often walk in this area of the park, and rarely do I see anyone playing on the frisbee golf course. In particular, if you'd like to play, head on out! Chances are good, you will have the course to yourself, plus or minus a few geocachers.
Did you know that frisbee golf or disc golf originated in the early 1900s? According to Wikipedia, "The first game was held in Bladworth, Saskatchewan, Canada in 1926. Ronald Gibson and a group of his Bladworth Elementary School buddies played a game of throwing tin lids into 4 foot wide circles drawn into sandy patches on their school grounds. They called the game Tin Lid Golf and played on a fairly regular basis. However, after they grew older and went their separate ways, the game came to an end. It wasn't until the 1970s that disc golf would be reintroduced to Canadians at the Canadian Open Frisbee Championships in Toronto."
