Ok,
I could start with the ole sea story 'This is the truth', and everybody would say I was full of it. BUT, let me tell you from "experience" a nice American forest grown Eastern Woodrat when skinned and gutted looks just like and tastes as good as any squirrel.
They are the ones that build the dens in the wood of piles of sticks, in those dens there are sleeping areas, food storage areas and bathroom areas, they are super clean. My 303 would skin'em out just fine.
If we had survived the plane crash on the mountain top, I would kill or trap one in a heart beat. I would grill it on a fire and when you wouldn't eat any I would just smile, lean forward and whisper 'you gonna die, sucker'.
Course I have also eaten alligator gar, burro nose, armadillo and several varities of snakes.....300Bucks
