I had heard somewhere along the line that when parked, a wooden prop should be placed horizontal to the ground; I vaguely remember it had something to do with moisture.

The Champ I fly has a wooden prop, and as I did the post flight I turned it (after triple checking the mags!) to be that way and got a lot of looks like I had a third eye in the middle of my forehead.

Is this one of those Old Pilot Tales, or was I correct?
