I have a couple of Styrofoam coolers that our Omaha Steak shipments came in. One is new and the other is a little beat. Once the food went into the freezers, they went into the garage. They both will hold water.
I used to use ones like these to transport fish when I was in the aquarium hobby. If someone wanted to keep a big bass in it while they transported for a weight (pin fish, etc.), they would work well.
Free to anyone who wants one or both. Next Wednesday is trash day so I'll be breaking them up Tuesday night.
