Darin Taylor is transient, in every sense of the word.Almost every day, he packs up the blue and white tent that he and his girlfriend share under the Tejon Street bridge. He stuffs it into a shopping cart holding nearly all their belongings - his girlfriend's oxygen tank included.He repeats the cycle with nearly each sunrise and each sunset.And he's far from alone.Far too few shelter beds exist in El Paso County, leaving homeless people with little choice but to risk their safety and break a city ordinance by camping, homeless advocates say.
