I was flying on Sunday and was about 7 miles to the south of FRG getting ready to land. I was at TPA (1100ft) and tower asked if I saw a drone at my 11 o clock 800ft. I didn't see the it but ATC said it was no factor and I could continue straight in. About a minute later, ATC said the drone was following me and was at my 6 o clock and he called up the drone to see if it was on the frequency. I never saw it but it got me thinking. It was about 5 miles from the airport at 800ft so it would definitely be in FRG's airspace. The drone was not legal to be in the airspace correct? Don't RC and drones have designated areas where they can launch from?
