Congratulations! I've never hunted muleys that time of year. We usually head out 2nd week of November. So, I imagine they'll be up to their usual routine, seeing as it's a while before the rut kicks off. Best thing right now is surveillance. Get some eyes on them (or have your friends w/property check up on them from time to time) so that you know what kind of pattern they're following. Google Earth is a great tool for planning out specific hunts. Know ahead of time exactly what land you'll be allowed on so you can have some sort of plan. Another thing to realize is that in MT we have been blessed with TONS of public land. Get familiar with the nearby nat'l forest, as well, and be ready to take a 300-yard (or more) shot! Good luck!
