Speaking about noticing themes in the pictures I have taken, it seems that Sam spends a lot of his time helping people move from one place to another.
He set up this Hay Wagon of sorts for his little sister and nephew complete with car seats and took them for a ride in the driveway.
I guess this must be why men like to do the driving. This must be part of the manly role, like Joseph leading Mary into Bethlehem and then leading the Holy Family into Egypt. I never realized before what a natural part of being a guy it is to help folks get from one place to another!
