A. J., Red, Elsie Lou, Mama Hill & Papa Hill in 1946

Mother's caption on the reverse reads, "A. J. Hill, Red Hill, Elsie Hill Smith, Mama Hill, Papa Hill."  Was this photo taken at the farm?  What structure is that to the left?   Red and Papa Hill are enjoying their cigars.  A. J. and Papa Hill seem to be dressed for working.  Are Red and Elsie dressed for traveling?  What about the car?

Has anyone noticed the little girl (or boy...) under the trunk lid?
