Rocket Car Wash

Where is the rocket?
I remember when this was Sparkle Car Wash way back when. My mum drove the 1959 Cadillac back around the very, very tight curve at the back. It was entertainment in a boring town, riding through the car wash.
It’s much the same today, though the name has changed and there doesn’t seem to be anyone at the exit to dry the car. There are plenty of «space age» lights still, telling you what’s happening to the car through the tunnel.
I believe that there are two levels (maybe three?) of car washes. I bought a book of 6 washes last year before Father’s Day when they were on sale, so I don’t recall exactly but the more premium wash includes the underbody wash. That’s a good thing in these states where the salt can build up over the snowy, icy months.
You don’t really have a lot of interaction with the employees. They take your money or car wash coupon, do a little brushing, and hooking the car up to the conveyor. Then, you’re on your way.
I believe that they have extra cost detailing services, if you’re so inclined. The automated system does a good job, at least on cars and minivans that I’ve taken there.
