​Aye, I've heard that about nudist colonies, and haven't gone to one.  Not
that I'm not proud, you see, but maybe not that proud.  In any case, not
the place for a married man and an introvert to boot, with a wife worth
looking at.

Thanks for all the info but I think you ducked the question (pun
intended).  Or maybe you don't know just how low a radar can detect
something.​

​ Is 'under the radar' still applicable?  Or maybe it would be a
satellite?  I know they can read newspapers from up there​.  But can they
scan for low flying drones?  Our defense dept. has to be working on that.
