I've had the good fortune not to run into any d-bag chuckers on the course yet, but I know it's bound to happen. I tend to go early in the morning, especially in the summer when it's real hot. I see lots of guys out there without shirts chucking around tie-dye champ Bosses as their only disc, but they're out having fun and have always been friendly and courteous. I have no problem with that. What does bother me, though, is when non-dgers wander onto the course while you're playing and refuse to move or acknowledge that you're playing. I once had a lady who insisted on walking around the fairways with her dogs without leashes (this particular park requires your pets to be on leashes) and she was in no big hurry to leave. I tried my best to be patient, but I was screaming on the inside. Even if you don't know what DG is or how it's played, isn't it a basic human function to realize when you're in someone else's way? Luckily her dogs weren't retrievers or else there would have been some major issues.
Going back to the 'chuckers always throw Bosses or Beasts' discussion, one of the big sports stores in my town that sells discs seem to be infatuated with high speed drivers and I think this contributes to the issue. I'd say 60% of their sales rack is tie-dye Champ Bosses, with quite a few Vulcans, Katanas, Nukes and even a Groove sprinkled in. For midrange discs? A Buzzz is your only option. Putters? Magnet or Aviar. It's easy to see how someone who doesn't know much about the game ends up with the plastic they do when it seems the sports stores in the area think high speed = sexy and only stock their shelves with it. Luckily there is a smaller, lesser known sports store in town that sells a little more variety (I picked up my first Roc there and never looked back), but unfortunately most people end up going to the bigger box store.
