Just don't get those hats near to anybody or you're going to have to pee on them. Probably wouldn't be the first time that happened at a wedding, but be careful nonetheless.
Dad was a Lieutenant Colonel in the Army Corps of Engineers. Mom & Dad got married at Ft. Lewis Washington after the war, and his men decorated this earth mover as their "carriage" from the chapel to the reception. This is a colorized black and white, and I especially like how they drew in a rainbow in the background.
