San Francisco Pride is a colossal celebration that has the entire city decked out in glitter. As long as it’s biodegradable, of course.

In its 46th year, San Francisco Pride is expected to draw at least one million people into the city to cheer for 200 different parade contingents on Sunday, June 26. But as any San Franciscan will tell you, you don’t have to wait until Sunday to start waiving those rainbow flags.
