Well for the second time in a week I've been run off by police for filming in a place I was sure was legit. I haven't been fined yet, but I'm sure at my lifetime limit for getting shocked out of my flight-reverie by siren blips and flashing lights. I regularly consult sites like Airmap and Don't Fly Drones Here, but their usefulness is limited since they function as blacklist type sites: they only indicate places where flying is 100% not legal. There are still many, many places where you can't fly that are as yet unmarked, which makes planning a crapshoot. The aforementioned runoff occurred despite my best attempts to find any rule or regulation that banned flight in that area, and came up with zip. Only after the officer gave me a specific code number was I able to find it, buried deep within an obscure PDF on a huge, sprawling website. I dislike walking a legal minefield while scouting locations, so what I'm looking for now is the opposite to Airmap etc. A whitelist-style site, that only shows places where flight is confirmed 100% legal (ideally including Northern California). Does anyone know of such a place? I haven't had any luck googling, since the only sites I've found so far are either years out of date or have horrible recommendations (Ocean Beach? sure, if i want to lose $1500).
