I agree about the airspace. After a certain height, I believe it's free air space. Just be careful flying on CA properties. It seems like they're not too sure about drone regulation and might be changing their policy soon. I went to Piney Run Lake in Carroll County on Tuesday and after being charged $10 for entry and flying for about an hour, I finally saw a no drone sign. The messed up part is that their no drone signs say that it's an order from the FAA, but on the B4UFly app, the area is not restricted. When I told this to an employee, he replied that drones can't fly in almost all of Carroll County. I thought it was crazy insane for Carroll County to be mostly flightless. Sad news, on Wednesday, I had my first big crash and mailed my Mavic. It was totally my fault and stupidity. Thank goodness I have the DJI Care Refresh and have to pay only $79 and not the $342 estimate I got today. Since DJI is replacing my Mavic, I hope it comes in next week. Can't lose these flying days! Always look above the Mavic to make sure it has enough space to take-off!!!
