@richrf,
Yea Rich, the domain name itself is great and very marketable. If anything, you could easily sell the domain to a developer! But I agree a golf course directory service would suit that domain very well, and would provide content that keeps a steady flow of traffic for ad revenues.
Just curious, how long have you owned this domain name? DnScoop claims it is worth $148,000,000! Ha! I don't think this could be accurate, simply for the domain itself...but the domain is definitely worth some cash. It is such a short, simple, and easily memorized name that it could be used as the homepage for a new search engine, or some other large scale corporate website. Actually, I think you could make this site much bigger than a golf directory, if you brought in a professional development team.
