Taking Photographs in Chinatown

This Saturday, I vow to travel into San Francisco's Chinatown, and take lots of cool photographs. I especially want to photograph the tops of some of the buildings on Stockton -- or is it Grant? -- Street, where colorful flags fly, and roofs often are covered in brilliant tiles. Maybe I will also take a few surreptitious photo's of people walking by, hoping to capture some interesting expressions. I will definitely photograph the colorful produce at the various produce stands. It should be interesting.
