I'll be going on an multi-day deep sea fishing trip where we are expected to catch between 150lb to 400lb of fish each (Yellow Fin, Ably, Dorado). I'll have a 3 day drive back home across the Midwest. Last time I looked into this about 15 years ago, it seemed like it was easy to buy/find large styrofoam ice chests (like 3 ft long.) Now it seems these are nowhere to be found.
What are people doing to transport fresh or flash frozen fish or any meat really on a plane / vehicle / boat where maybe dry ice is involved? Am I stuck with buying Igloo coolers at $50 each? Or are these foam ones I used to pay a few dollars a piece for still available and I'm just not looking in the correct place?
