It couldn't be worse than the tour I had of the fish food plant in Astoria in the 80's. I still remember that smell. Nothing like barrels of rotten fish. gag And it might be interesting to see how the process works.
Been there, done that. Didn't win it though. The company I was working for was doing some engineering consulting work for them and I got a tour of the facilities from one of their engineers. Nice place, and most of it doesn't smell too bad.
