I must say as usual we had so inventive answers but I must give one person special credit for being so observant. Craver VII not only got the identification he realized where I had taken the photos. A hearty WAY TO GO is in order. Craver has some neat shots with his camera set-ups.
Craig did beat Joan today by guessing a rivet on a galvanized part, SORRY JOAN. I wonder if he has one for this week. Probably, someday, someone other then his brother Scooter will win. Can you spell nepotism, I can.
