The best way to glimpse what you’re missing as a nonmember of the country club set is to attend the annual River Oaks International Tennis Tournament. While the ticket is pricey, you don’t need one to get on the grounds, only to enter the stadium. Sneak in some alcohol, because — and this is a recent development -- you must be a member to order beer and mixed drinks. Once you're settled, gawk away. But a word to the wise: Stand still, wherever you are, during the national anthem; otherwise, some stiff wearing khakis and a navy-blue blazer may hassle you. On your way out, don't miss the miniature horses tied to the trees in some rich jerk's front yard -- a gawk-worthy site if ever there was one.
