chippewa inn is next to the old customs station on sag. look for government island, that's where the old customs station was located. building is still there but nothing is operational anymore. most likely, that is where you flew from.
interesting article about
Dicky Powell and Chippewa Inn .
i don't think there are any "outfitters" on the canadian side of Sag. there is
Sagonto which is where many people purchase their canadian live bait.
of course, depending on when your trip was, there could have been more businesses many years ago.
can you name any lakes you traveled and maybe we call all help you piece it together?
