Joe, great point about elevation changing arrow flight. As it happens we will be much lower down, so that shouldn't be a problem. I do intend to take some blunts for grouse as that is also a goal of mine. And of course, practicing until I leave. My brother and I put on packs yesterday and walked mile laps and every time we got backup the hill we would take 1 shot. We were pleased with our shots and both feel we are as ready as we are likely to be.
Thanks Greg and gutshot, still a lot of unknowns (like any hunting scenario) but we are doing our part.
