I have caught a few grayling in the Gallatin and the lower Madison, as well as Grebe Lake in YNP. I also found them in a lake here in western Colorado:



Pretty fish, they seem to fight about as well as a trout of that size, but then I have never caught one large enough (the one in the photo is about tops) to give me much trouble.
