Hehe, I have only ever seen it in farmers markets. They tend to have the good stuff! It costs a bit but I like to get a bit of whatever exotica they have when I do to the local one on top of my go to Bison burgers which are fucking ace.
A Nessie steak would be tops. Could keep a family of Nessie's in a farm like salmon! Minus the lice of course 😀
