Droplabs is a downtown Los Angeles free hackerspace / coworking space where anyone who works off a laptop is free to use the space and get work done. Extras like high speed wifi, 2nd monitor or drinks cost money. The people are mostly developers, Drupal and iOS, working on projects. But lots of different tech types show up. There's 3 companies operating out of the space. www.droplabs.net
