Bumped into a colleague or friend that you did not know they were either a hobbyist or provider. I have never gome to a M&G, but I wonder if anyone has come across a situation like that.

And in multiple places...both NYC and Vegas. Overall, it was cool.  I suspect we both know, and I know for a fact that he has seen my ATF, and vice versa, multiple times.  Just have be cool with it...
