In the 1940s, Crowl teamed up with his son-in-law, Herman "Buster" Burris. They expanded the business to include a café, an auto repair garage, and an auto court of small cabins for overnight rental by Route 66 travelers. Buster Burris himself almost singlehandedly created the town's infrastructure, some of which remains semi-functioning today. Burris even brought power to Amboy and Roy's all the way from Barstow by erecting his own poles and wires alongside Route 66 using an old Studebaker pickup truck.
