Estimating Distance

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.

Distances are to the center of the green.

Red flag indicates the pin is at the front of the green, white is middle, blue is for the back pin placements.

Man, I wish they would do that in Denmark.

Best I've seen so far over here was a grid-layout on the scorecard, depicting 6 'zones' for every green, and then a sign at first tee telling that this days pin-position is "5".

Mox, are you crazy?

I'd much prefer the map/pin method, as you get a better idea of what you're shooting to - especially on a long skinny green. If it's in the back, you know that you generally have another 10 yards to go to the flag (past middle).

My course is even worse - red flag for the front half, yellow for the back. And the flag can be anywhere from 2 feet forward of center to the minimum distance from the fringe...
