Fishing on the Powderpoint Bridge and having a big'un break the surface to hit the Storm Shad I was just pulling out of the water.
This happens at least once EVERY year. I laugh afterwards,

because it's usually when I've gotten relaxed, and let my guard down.
Having the fish jerk the rod back like that always gets me going.
Same bridge alone late on a moonless foggy night, having the feeleing that I could turn around at any second and have some apparition (ghost) right in front of me.

When the hairs stand up on the back of my neck, I just change locations.
