I haven’t yet found photos of the trip to Washington or to California that you’ve described. But here is the 1948 Chevrolet and here are the people involved.

Taken in front of 1598 W. 10th in Junction City about 1948. Looks like it might have been Easter from the way everyone is dressed. Names as follows: Back row (L-R): Dad, Mom, Donna. Front row (L-R): Clara, Kathryn, Dorothy, Art.

I thought the planters on the roof of the porch in the background were interesting.
