Just joined today. Reading this thread gave me an excellent idea.
I went to http://terraserver.microsoft.com/ and got an arial view of the course I play the most at.

I blew the image up a bit and broke it up into 3 hole segments. Now I'm outlining the fairways,greens, teeboxes and hazards to show a more defined look. Also I'm pencilling in some changes that has been done to the course since the picture was taken.

Now I can't wait to get to the course so I can start getting some yardages.

The main reason I'm doing it is we have a severe dogleg par 5 and the yardages are horrible on it. They measure to the corner then to the green so going for the green is guess work at best. 250 could actually be 190. Plus there is OB on the long side so I always guess short and end up in the bunker.

Great forum!
