This little saying was told to me by one of my buddy’s older brothers, Emilio.  Their family grew up in Irvine, CA and to get to school everyday, they had to drive over a bridge.  Everyday, throughout elementary and middle school, their mother would tell them to lift their feet up when they drove over the bridge.  He recalls his mom telling him pick up his feet and look out the window because they were ‘flying’.  Unfortunately, Emilio’s mother passed away a few years ago.  He says when he drives over a bridge now and lifts up his feet, it gives him a fond memory of his mother.
