“LA is the apocalypse: it’s you and a bunch of parking lots." - Geoff Manaugh
There are metered parking spots right across the street from the venue, but please remember to feed the beast. The Santa Monica Parking Enforcement is an eager bunch and will ticket you if the meter runs out.
There is a public lot on the other side of the park that is about a block's walk from Refactor Camp.
Probably easier to ride share or take the Expo line which stops across the street from the venue.
