There's only one real takeout and it's not possible to short cut it. Yea, you've got 2-3 miles of flat water, but I'm sure you are a hard guy and can deal with it.
The takeout is at the confluence of the North Fork of the Gunnison with the Gunnison. There's an outfitter store right there--I forget what it is called. It's in all the guide books.
It's a pretty run.
