tedryan10, Speaking of Three Sisters Wilderness, camping at the base (or very near the base) of the Hayden Glacier is pretty awesome. The views to South Sister/Middle Sister/Broken Top are psycho-fabulous. All you need are Pterodactylus flying around and you feel transplanted to Jurassic Park. If I recall correctly, you want the Pole Creek Trailhead. More info here http://www.summitpost.org/north-sister/150530 Recommended.
