I have never used Golf18Network.com, but I am hesitant to try. I was browsing some of the tee times around me, and I noticed a few for one of my favorite local courses, The Club at Shadow Lakes in Aliquippa, Pennsylvania. The tee times were for the upcoming Monday. Seemed like a pretty good deal until I remembered that this course is CLOSED on Mondays! So what would have happened if I booked a tee time...? It would be interesting to hear what Golf18Network.com has to say about that.
