alcoholics anonymous:

a photographic journey through its history...

Bill and Lois Wilson went scouting investments during the mid-1920's on their Harley Davidson.
Lois often remarked that Bill usually let Lois drive while he sat in the side car.
She said Bill preferred her doing the driving. Lois was really the Harley rider but Bill showed off here.
