People talking during my preparation and during my throw or putt doesn't bother me. A change from silence to noise can be distracting for sure.
I will be quiet, myself, during people's throws, though. I have some interesting friends who get all out of whack with any noise at all. And the only time a car drives by, or a dog barks, or shots are fired is always when they're throwing.
We have a course here that's directly across the river from an outdoor shooting range. If anyone wants to work on their mental game this course is good for that. :gross:
