John:
Those are both fairly small towns and I am not aware of any gun shops of interest. There is a fellow that posts here that lives in that neck of the woods and he may be more informed on current status.

Not sure on your route to Iron River. There used to be an interesting selection of old american classics at the Seney general store, but they are located on M-28 and you may be gettig there via U.S. 2. Seney would be 30 minutes out of your way.

By the way all of the grouse in Iron County and Dickinson County died off years ago - essentially extinct up that way. No reported sitings in at least 5 years. The Wolves and Cougars are so thick it is not safe to be in the woods without the support of at least a company of Marines - heavily armed. Strongly advise you consider area around Montreal, Canada. Much closer to New Jersey and not nearly so dangerous. The outfitters up in Montreal will guaranty you 10 grouse per day and all the woodcock a young dog could want.
