I just lost a weekend. I ain't too anxious to find it. Instead, I sure wish I had gone fishing with McCarthy and the boys like I'd planned.I drive a beer truck for a living, but here it is almost noon Monday and I haven't turned a wheel. Sure, I get beer wholesale and I have been known to take some advantage of my discount. But that wasn't what happened to this weekend.Instead of fishing or bowling or poker or taking the kids down to the amusement park over Saturday and Sunday, I've been losing sleep over an experiment.Down at the Elks' Club, the boys say that for a working stiff I have a very inquiring mind. I guess that's because they always see me reading Popular Science and Scientific American and such, instead of heading for the stack of Esquires that are piled a foot deep in the middle of the big table in the reading room, like the rest of them do.
