I haven't fished the Hump a lot lately. "Back in the day" 20+ years ago there were almost as many sleds as drift boats down lower at least. There seems to be a higher tolerance for sleds on the Harbor streams than farther north. I like sleds, by the way, only as long as they're not on the same stretch of river I am fishing.
not to mention, back then most were 14-18 footers tops, not the huge 8 foot wide 22' guide barges with 200hp outboards you see everywhere today.
