I don't know about the Catawba area, but Butch and Denny's in Curtice is almost always open until 9:00 unless the weather is bad enough that nobody in their right mind is out fishing.

As for what to do with them, basically keep them cold. Pack them in ice or put them in the fridge. The fish cleaners just put them in a big walk in cooler for the night if they have more than they can clean in one evening.
