Festival season in San Francisco.

It's my favorite time of year in San Francisco.

Festival season.

Summer is the time when San Franciscans love to party. The season kicked off with beta breakers last month.

Beta breakers started as a normal running race. It was started after the

1906 earthquake as a way to cheer up the city.

Well, it has certainly evolved into a cheerful event.

Beta Breakers still has a running race.

Professional runners, followed by amateur runners, start the race.

However, most of the 65,000 people who participated this year were not runners.

Rather, beta breakers is now one huge moving party.

People wear crazy costumes.

They build and push huge rolling floats, bars, and other structures.

Some people walk or run naked.

Many people push or pull, full kegs of beer, or coolers full of bottles.

The party starts at the bay on the east side of the city and winds through the Hayes Street

neighborhood, then through Golden Gate Park to the ocean.

Along the way, houses next to the route play loud music and host house parties.

Only in San Francisco will 65,000 people walk 7 miles and party at the same time.

Another huge festival is the annual Gay Pride Festival.

Of course it's probably the biggest in the world as San Francisco has long been a center for

gay rights.
