I do have the benefit of the Pacific Ocean being on one side of me, so not too much coming from that direction, but yeah, all my life I never really had any problems with this sort of thing even when I've lived inland/mountains/other states.
I did play with a guy for a number of years though, bass player, and the guy was some kind of human superconductor. He'd pick up all kinds of crazy signals that would go away if he put the bass down or someone else was playing through his rig. And he'd fry amps all the time by just touching the knobs.
