Of all the gall. Houston goes nuts when Bob McNair lands a pro football team for the area, or when Grand Prix racing adds the city to its circuit. But there's not even a tax subsidy or muted shout ready when Diamond Lanes operator Jimmy Young attracts one of the sports world's most coveted events to the Houston area: the Professional Bowlers Association tour finale (the Lone Star Open runs November 17 to 21). Hand it to the blue-collar citizens of Pasadena. They know their bowling, and they know Diamond's the best. The 32 lanes are kept in flawless condition. There's a pro shop, lessons, enough house balls to suit anybody and the musical lights-out rock-'n'-bowl extravaganza for the teens on Saturday night. Plus, there's the new arrival: a full-service pizza restaurant right on the premises. If Diamond's good enough for the pros, it's definitely the best for the rest of us weekend bowlers.
