I have hunted 7 before and there are plenty of elk. Killing a cow should be fairly easy.I will send you a PM when I get some time.
I've lived in Flagstaff the last 3.5 years so I know the area fairly well. 6B is a pretty cool unit because you have the choice of either hunting in the pines (above the mogollon rim/Sedona) and down in the junipers/pinyon (pretty much everything below the rim). Finding a place a ways away from roads can be difficult. They did "close" several of the roads last year when the new Travel Management Rule went into effect, but most of the roads are not gated and most people will drive down them anyways. If I were going to camp for a week to try to get away from people I would head along the eastern rim of Sycamore canyon north of the rim (assuming the snow hasn't pushed the elk into the canyon). Good luck!
