I am brand new at this and was just wondering. If I buy a trout stamp in TN is it good in other states? I use to duck hunt and I know the duck stamp was federal and was good in any state. All you had to do was buy the correct hunting license. Does the trout stamp work the same way?

thanks in advance,

PS: One other thing, if I never get my fly out of that tree and in the water, I will probably never catch a fish. That being said, think I need to waste the dough on fishing license?
