Every Wednesday over at the quaint and centrally located Desert Storm Park polo grounds, bicycle maniacs test their mettle during lightning-paced warfare on two wheels. Similar to the traditional yuppified fare, sans the prohibitive price tag, bicycle polo is actually an old sport that's been revitalized in recent years. Its birthplace is believed to be India about a hundred years ago when British troops used bicycles to hone their equestrian polo skills. The urbanized non-equine variety features two teams of coed-friendly riders slugging it out on a 100-by-60-yard grass field with the simple objective of outscoring the opponent. Admission is free, and mallets are provided. All you need is a bike and a healthy pair of lungs. A helmet is a good idea, too.
