WINONA, Minn. – If you gotta go, really go, you don’t want to be over at the Bud King Ice Arena on East Front Street. Some joker blew up the porta-potty outside. Police Chief Tom Williams said the tool of destruction appeared to be fireworks. Not much was left but melted plastic – a loss estimated at $2,000. A passerby ran across the meltdown about 7:40 a.m.
