I must say that in 50+ years of fishing I have only been approached a few times, and most have been very pleasant, none have been rude.

There was one that patrolled the Sky years ago that had a very bad rep though, Abrams I believe his name was. Stories of him pulling a gun on a guy at Reiter, then the guy taking the gun away from him and reporting him. Stuff like that was common. I never ran into him, but friends did, almost every encounter was a bad one.
