This thread has been fairly interesting, and kinda confirmed my hunch, there is no consensus on how to use the trails. I suppose that means whatever I do is acceptable

I haven't been using headphones, and I *have* been calling out "on your left", but honestly I think I'll at least go with 1 ear headphones and i'll call out only when it looks like the person will react how I expect them to. Way to go internet, you've ruined yet another cyclist.

PS, I'm not racing anywhere. Just PEDALING around for exercise. Doesn't mean I can't be regimented about my pace and breathing. I'm in cargo shorts and a T, and I couldn't spot lance armstrong in a crowd of 5 people to save my life.
