Paul,
There's always someone out there willing to come over and give you their opinion, regardless of whether you want it. The gun ranges seem to have their share, shotgun ranges less than pistol ranges though.

I've noted that for some reason the boldest of these characters is often older believes giving his opinion to a younger person is his god given right, regardless if he knows them or knows the younger person's depth of knowledge. Their presumption must be that since they're older, they must know more than someone younger. It's often laughable, but sometimes maddening, and always irritating. I've had more than one come up and pick up one of my nicer guns and start messing with it without asking or knowing me. I've been on the recieving end of this a number of times.
