How my confreres come up with ideas for their columns I have no idea, but the process is probably more studied and logical than mine. This may seem oblique, but I've been thinking about propellers since recently deciding it was time to quit talking and take action. So I presented myself at "Mother's," a tattoo emporium in Covington, Kentucky, where a nice guy named Brett etched little wings just below my waistline in back (known in some circles, I believe, as a "tramp stamp"). They looked great but we agreed the design lacked something. After three minutes of exhaustive thought and consultation, Brett added a propeller, and now, yes, it's perfect. I'd show you but I don't think the magazine would publish the picture.
