With a long-planned weekend visit from his parents looming closer, local homeless man David Ruffner told reporters Friday he has been scrambling to come up with things to do with his mother and father during their stay. I dont know. I guess I can show them my spot under the bridge here, but thats only going to kill an hour at most, said Ruffner, 38, speaking loudly to make himself heard above the din of a train passing overhead. And of course Ill give them a tour of the park where I sleep when the weathers nice, and direct them toward a discreet place to defecate, but after that Im gonna be a pretty boring host. Sighing in apparent resignation, Ruffner confirmed he would probably end up walking around the downtown area with his parents and maybe grabbing dinner from a restaurant dumpster.
