Finding places to fly can be difficult: BR> How to buy a drone in 2018 - CNET
In New Jersey and work in New York, and it's becoming increasingly difficult to find places to safely -- and legally -- fly. US national parks are off-limits, and in New Jersey so are all state parks. The county and municipal parks around me all have different regulations regarding RC aircraft. And then there are the no-fly zones, which makes much of New York out of bounds as well as just dangerous, because of buildings, people and cars. Before you buy a drone -- even a toy one if you plan to fly outside -- you'll want to visit AirMap or Mapbox to check no-fly zones for places you intend to fly. In the US, you can also download the FAA's B4UFly app to check your planned location. These don't cover state or local ordinances, though, so you'll still need to check them to see if you're OK to fly.
