go for it!
If you have the time and want to extend you trip/ views put in at dewey bridge. On this trip the towers will pop into view after a short time, but no whitewater is added
If you want a quicker, 14mile 1/2-3/4 day trip put in at hittle bottom in sight of the towers.
You can take out several places, as any river map will show. However I'd say float on as long as your time permits. really even though there is a road near by, and the rapids are few and far between, it's one of the most scenic and accessible stretches I've even done.
Well worth it, enjoy the float
