I recently discovered OpenWiFiSpots.com and have fallen in love with it. I know some writers prefer to be away from the internet when they work, but for those screenwriters who like to be able to check facts, research locations, or just take a break and check their email, this website is invaluable.
OpenWiFiSpots.com has complete listings of coffee shops, restaurants, libraries, and all sorts of other public locations that have free wifi readily available throughout the Los Angeles area.
Look for wifi hotspots within specific neighborhoods or specific types of locations. This is an amazing resource for finding your new favorite writing spot. Plus, if you’re not LA-based, the site has listings for a number of other major US cities.
