and look at the guy with the broom handle roof scrubber...
just to set the record straight, the first production line car wash was in Portland in 1911, though most people think it was Detroit in 1913. (Detroit has better marketing)
The first auotmated car wash was Paul's Automatic Speedy Best Wash, 1946 was the year it opened
