Seattle residents will light up this holiday season in celebration of the first anniversary of Washington state’s legalization of marijuana.

After a three-month battle, city officials approved a weed festival at the Seattle Center’s old Fun Forest amusement park. Pot advocate Ben Livingston plans to feature light music, food and pot smoking for up to 500 people behind a double fence, or smoking “moat.” The state prohibits people from smoking pot in public.

The free, adults-only event is open to the public.
