Those of you familiar with West St Paul, may recall the Signal Car Wash during it's prime just off of Robert Street, behind the old Signal Hills Shopping Center. I believe it is closed now as it was a Sunday around 2:00 at the time of this photo. It would have been open during it's business hours. I do recall visiting the car wash when I was much younger. It's the automated type of wash. Drive your car in and watch it travel down the track in various stages of wash and rinse. The customer would stand behind glass windows and watch as the vehicle progressed to the finish line.
