Yeah, that surplus store sold me a lot of ammo and various odds and ends over the years. I often wondered whether it had been around long enough to have been the inspiration for "Grogan's War Surplus" in Pat McManus' stories.
I'm old enough to remember when the first water park expansion was the new attraction.
The shittiest part I think is that they weren't insured. If they own the lot then they have something but that building is gone. It was there for 43+ years so very well could have been what Pat wrote about.
