Here’s my 2 cents...use maps, technology like google earth, and an updated gps detailed map they you pay extra for, and get out there and be mobile. It sucks but you’ll have to burn a little boot leather to see how your planning pays off. I’ve run into strange things before all the tech was available like a road ending in someone’s garage where it should have gone into public land, private land cutting off what looked like access, areas where there are no animals, and areas where ATV’s are necessary to get into the animals. The updated GPS software and area maps are a HUGE help for showing trails and what can go where..I basically start looking at elevations and then access and plan to see animals about.5 to 1 mile and farther back, where there are NO ATV trails within reason. Basically I start by looking where ATV’s can’t go and work from there..CO has Good numbers of elk, It usually warm and sign isn’t always apparent, so hunting early and late are key, even though it’s a pain to be out so early and late without a plan. There aren’t many areas I have been through that don’t hold elk, but that’s the hunting part.
