"So maybe I’m going to keep my drones the way I keep my firearms—unregistered."
Update: From the comments, "In 2012 Congress
passed the Modernization and Reform Act of 2012 which reads in part:
"The Administrator of the Federal Aviation Administration may not
promulgate any rule or regulation regarding a model aircraft, or an
aircraft being developed as a model aircraft". Congress defined a modal
aircraft as "‘an unmanned aircraft capable of sustained flight in the
atmosphere, flown within visual line of sight, and flown for hobby or
recreational purposes.". Sounds like a drone to me."
