Plan a summer backpack trip into whatever area you pick out on the maps. It will give you a much more realistic assessment of how to plan your hunt than showing up to the Frank for the first time during October/November
If your new to 27 you should probably fly in first. The limited road access can be dangerous. Every few years guys get trapped behind the passes after a storm dumps feet of snow. Can even happen in September and either you pay thousands to get your rig out or you wait till next summer to retrieve it. The fly in options are very reasonable and you will be in animals within day hiking of most strips. If you are willing to go several miles from the air strip you will mostly have it to yourself. But as mentioned several miles in the church is a brutal proposition with a load. That said it is a special place to hunt and enjoy.
