There are too many details and quotes and neat stuff about the US 23 Drive-In (Flint MI) from this Flint Journal article for me to summarize, so you ought to go read it. The 23’s general manager said the biggest draw of the summer was Ice Age 4, partly because it came out when he was running more than just weekends.
But don’t think the relentless need for improvement has overlooked the 23. They plan to add fountain soda machines, because customers have been asking for them. Yeah, I remember when the old Comanche (Buena Vista CO) was open, it just had a cooler full of soda cans. Not nearly as nice. Good luck, 23, and please get the kind of machine that dispenses crushed ice.
