Speaking of speed ... ever been to the Louisville Slugger plant? I went some years ago, but at the time they had a pitching machine with a "catcher" set up to watch, and I think the machine was set to throw about a 100 mph fast ball. It was incredibly fast ... actually hard to follow.
I used to think of myself as a decent hitter. There was a batting cage near a Putt Putt course in sort of an entertainment area, and you could get in and select your speed, all the way up to what they called Major League. Well ... I got in there and tried Major League, and it was downright scary. I couldn't hit a thing.
