yes jetman.. ppl do answer questions here. The problem is that when the same question is asked for the 2,549th time, the answers get stale.
There is a search feature. Simply type in Multiplayer, course, etc and you would have found your answers.
Or, you could have looked futher down this page.
To specifically answer your question... yes, there is only ONE (1) multiplayer course available at one time. Currently it is Bethpage Black front 9.
And, continuing, there are only TWO (2) courses that will allow stroke play, 18 holes, single player.. Kiawah and Bethpage Black.
There are FOUR (4) "Closest to the Pin" courses available. THREE (3) of them can be accessed from the "Play Now" button... Bali Hai, Wolf Creek, and Edgewood Tahoe. The 4th, St. Andrews, can only be reached from the Tournament section.
See? Most of us are glad to help, but we would like to see a bit of effort on your part via the 'search' feature to keep us from answering the same question for the 'umpteenth' time.
Have a nice day.
