Yvonne certainly is a fine looking gal!! I can tell you from knowing her that she was indeed a steelheader. At the time the book was done she was engaged to Clint Delargo who is an amazing steelheader and in the books Vedder has written. Clint broke off the engagement because Yvonne claimed he fished to much!! Talk about your die hard steeelheader!!!
As far as the video goes, the video that needs to be shot is a new one on proper catch and release techniques on steelhead.
There is one out now and is offered by the state. It should be more readily accessable though and distributed to all. It was shot up in BC to show proper fish handling techniques.
