To swing back to the conversation about pedestrians on the course, it bugs me how some disc golfers try to get their attention. We're on the tee pad, a family starts taking family photos 250 feet down the fairway, and the guys on the pad whistle really loud, wave their disc in the air, and shout, "hey, we're gonna throw here!" As if the family as any bloody idea what "we're gonna throw here" means.
I much prefer to walk down to them and have a civilized conversation. And not walk 100 feet closer and whistle and shout the same thing. I always try to be a little coy about it. "I hate to be a party pooper here, but there's a frisbee golf tournament going on here and people are going to be throwing frisbees right across here. These little guys are pretty hard and can hurt pretty bad, yadda yadda yadda."
And as much as I hate the term "frisbee golf", it really works better than disc golf when talking to pedestrians. "Dis gulf? Des colf? What are you guys doing out here?"
