New, simpler route for the next CicLAvia

The map for October 7 comes up Figueroa Street from Exposition Park, and meets 7th Street which will be open to bikes, skates, strollers and feet between MacArthur Park and Spring Street. Spring is then good north into Chinatown, with a little zig over to Broadway. It's all very contained in the central city except for a leg to the Eastside via 1st Street, Central Avenue and the 4th Street bridge, then back up Boyle to Mariachi Plaza and a bit beyond to Soto Street.
