Follow that as it curves to the LEFT and turns into Broad Street and passes under Highway 99 (Aurora). Turn RIGHT at the next street, which is Harrison. Then turn RIGHT onto 5th Avenue. Follow that past Mercer to Roy Street. Turn RIGHT onto Roy Street. Pass through the stop sign. The RUINS is on the next LEFT HAND corner of the street. There is no signage on the building other than the numbers 570.
