pics and video in article A recent Wednesday at 3:34 p.m.: Walter Biondi bought his first shotgun when he was 17 and shortly afterward headed to the Pacific Rod and Gun Club to start what has become a lifelong passion for skeet and trap shooting. It didnt take me long to become acquainted with the gun, Biondi said. Now at 93, he is oldest member of San Franciscos only trap and skeet shotgun shooting range. The range occupies 14 acres on the southwest edge of Lake Merced. The club is open Wednesdays and weekends, and there is rarely a day Biondi isnt eager to be there. Biondi pulls up in his blue Toyota Camry, opens the trunk, zips up his tan shooting vest, slips 25 shells into his front pocket, and takes out his favorite double-barreled Browning shotgun. He shuffles toward the first of seven stations facing the water. He loads his gun and yells, Pull. A Day-Glo orange disk flies toward him at 40 mph from a green tower. Biondi follows the target for a second or two before pulling the trigger. It is obliterated over the banks of the lake. He opens the back of his gun. The barrel smokes from the rear as he catches the used shell in his hand. A smile stretches across his face. He reloads. With views of the golf course across the way, the club has existed on prime lakefront property for 78 years, operating under an antiquated month-to-month lease facilitated by the city. In July, the city Public Utilities Commission said the deal was over and the club needed to get out unless a modern lease agreement could be reached. I think another 78 years for a gun club on that property is probably not realistic, said Steve Ritchie, a PUC assistant general manager. Ritchie cited an environmental cleanup of the site with a price tag of more than $10 million from decades of contaminants left by old targets and ammunition as a potential deal breaker, even though the club no longer uses those hazardous materials. Pacific Rod and Gun Club spokesman Fred Tautenhahn said the club doesnt dispute the environmental issue, but added that it has hired its own environmental firm to appraise the cleanup costs and that its findings were about half of the PUCs estimates. He said he hopes the club can soon reach an agreement with the city. For members like Biondi, an agreement couldnt come soon enough. Walt has been there his whole life, Tautenhahn said. Obviously when he hears eviction notice, those are scary words. It makes him a little uneasy. Biondi said: I look forward to the camaraderie of the club. It gives you a reason to want to do things. Id hate to lose it. It means an awful lot to me.
