SAN FRANCISCO - Huge crowds are expected for San Francisco's 38th annual gay pride parade as revelers celebrate their newfound freedom to marry.

Sunday's parade along Market Street may resemble something of a wedding march. The county clerk's office was busy Friday handing out marriage licenses and handling wedding ceremonies. Same-sex marriage has been legal in California since June 16, after a state Supreme Court decision.

Overseas, gay pride marches in the Bulgarian capital of Sofia and the Czech Republic city of Brno (BUR'-no) came under attack Saturday by extremists who threw rocks and eggs. No serious injuries were reported.

In Paris, more than half a million people danced through the streets beneath a river of rainbow flags.
