Hi to All,

As a newbie, I have question about estimating distance. The courses I play typically have a 150 yard marker in the form of a tree or shrub. Is this distance measured from the center of the green or from the edge of the green?
Also, I've noticed that the pins are red, white, or blue on different greens for the same course. What's up with that, anything?

Thanks in advance.

Jack T.
