How much time have you got for this?
In a perfect world I'd be heading out Monday the 29th.
After checking out the lay of the land its not really possible to make a route in one end and out the other. Plan is to wander along the western edge of the National Forest and head into the mountains in search of camp spots and awesomeness as I go. First day is looking like 4 hrs to the border at Carway, AB, (from Red Deer), then another 2 hrs or so to Coram, MT, with an option to take the Going to the sun road or a larger highway further south. From Coram or more specifically Martin City there is access to quite a network of park roads/trails to be explored, most if not all of which is a one access point kinda deal until things begin to spread out. Plenty in there to occupy several days from the looks of things. Coram is under 4 hours by highway to Deer Lodge, so I may end up in the same general area for a few days before making my way to Deer Lodge. Not much of a plan, decisions about what to do when where whatever will be made on the spot as required.
