DENVER (AP) — Some revelers on San Francisco's Hippie Hill are complaining that the 4/20 marijuana celebration was less free-spirited than in the past.

Security checked IDs and turned away people who didn't have them, leading to angry exchanges.

City officials issued permits for medical services, food sales and security without formally sanctioning the event.

Merchants received permits to provide food trucks, portable toilets and erect a fence around the perimeter.

Joints and pot edibles were sold informally.
