“Santarchy” is an annual city-wide Santas-only pub crawl. This flash mob type event brings together hundreds of slightly sober people dressed in Santa costumes parading around the city, visiting landmarks (like walking down Lombard Street) drinking at bars and causing general mayhem.

And just so you know, wearing a santa hat isn’t enough… get yourself a full-on santa suit.

Santa will be in Washington Square Park around 3PM, but all other exact times and details are TBD.
