OCEANSIDE — The row of tents lining a side street near Oceanside Boulevard looks alarming at first sight, and anyone passing by might expect to see the area overrun with the trash and clutter generally associated with homeless encampments. A closer look, however, reveals the area is spotless. The tents look new, clean, and in a uniform order, with each one separated by a short, red, tented storage bin. “We understand that trashing this area is the number one reason why people wouldn’t want us here,” said Rodney McGough, a homeless man who lives at the site and has led the effort to keep it clean.
