The four new basketball hoops at the 12th and Park Recreation Center just south of downtown attract players for much of the center's operating hours, from 10 a.m. till 6 p.m. Even when it's raining, you'll usually find a solitary player practicing free throws. The new courts are equipped with smooth blacktop; fresh white lines; red, white and blue nets and dunkable rims. If there's one downside to the courts, it's the double rims. Yes, those contraptions where one rim is welded on top of another. It's to help them last longer, but as anyone who spends five minutes shooting on them can tell you, the ball will bounce out of the hoop with greater frequency and speed, like a basketball at a carnival game. That one downside politely noted, these new courts are surrounded by green fencing and are equipped with two benches for watching, a modest parking area and a constantly changing audience — the commuters on Tucker, stuck in traffic.
