No music for me either. I like being out and hearing nature, it's part of the disc golf experience .
About a year ago at DeLa there was a group that was playing some nice jams and it sound good even from a distance, then I saw them and found out why...they had a wagon with a full on stereo system amp, speakers, and a sub. Looked like a pain to drag around. Didn't bother me as I am rarely serious about my game.
Really. Hmm. Every time I'm there I run into people listening to Pink Floyd or Jimi Hendrix. I generally don't play on weekends tho.
Funny, as I'm typing a vehicle drives by with bass that rattles my windows and I'm pretty sure I could feel it in my chair. That annoys me more than any music on the course.
