I once went on a portaging trip with a guy that carried 2 rods and reels, a full mutli-tray tackle box and one of those big 'ol metal coleman coolers, stocked with 2 bottles of Screetch (Newfie whisky) and 2 cases of rootbeer. Of course he also had a kids-sized tent with a napkin-sized fly, an old army wool blanket for a sleeping bag, and the only extra clothes he brought were a rain jacket, and 1 change of socks and underwear.
The funniest part was that before the trip, he told all the girls going on the trip that he was going to go through our packs to make sure we didn't bring anything we didn't need.
EDIT: A week lugging all that suff through Algonquin Park, and all he caught were grass bass and a cold.
