“I am 72yrs old. Flew as a kid. I fly in my front yard and street and at the local fields parks, float fly at local lakes and ponds. There has never been any safety problems. I have friends that do not have a PC or cell phone. Where does this leave them? I do not be leave all of this is necessary This will destroy our hobby.. i would like to teach my grand kids the hobby.I also have a glider and so do a lot of friends.This will not work for them.
