One of the last great feedoms in this country is a VFR non-radio bimble outside CAS, with no-one even knowing you're doing it.
I can see the freedom bit, and very much agree, but what is the benefit to YOU in being able to do "it" without anyone knowing you are doing it?
The reality is that lots of people know you are doing "it" (they can see you on radar) but they can't see how high you are doing "it", so they are compelled to assume that you are doing "it" at the same altitude as they are, and they are trying hard to see you (to avoid a possible colission) when in reality you are say 3000ft below them. I can be flying at FL050 under a RIS and gets stacks of traffic reports which I can't see any trace of even if VMC on top, because they aren't transponding.
I think Mode C should have been mandatory years ago, on all planes which are normally powered etc. Controversial, yes of course.
