tdman:
does anyone know of someone who is constantly playing the same course?
There are some that do that. I can think of three reasons some do it:
1. Temporarily to learn a course better.
2. Temporarily (on an easier course) to try and lower average to tier up.
3. To challenge others for match play on "their" course.
There may be others - but I have done #1 and I know others that do #2 and/or #3.
Can't name names here in the forums.
