I applied for a colorado tag for unit 24,12,etc for the first rifle season. At this point I'm leaning toward unit 24. This will be my first time for elk and out west. I'm planning to set up a camp near my truck a hike in daily. What are some things I can do to help narrow down an area to hunt? Since I'm coming from pa I won't have the opportunity to put boots on the ground before hand! Thank you
