I know a few places i could point out on a map where mule deer are. You just have to do your part and scout. You have to find the paths the elk make, where they cross and what day. I got one heard figured out already. If you cant find a mule deer in 6 years of hunting in colorado, you need to find a new unit or start walking more. A lot of hunters stick to the roads and think they will find something to shoot at and thats not always the case. I can see hiring a guide if you are in hunting moose/grizzly/ other not to common animals, but for elk and deer, its pretty much look for areas that have a high number kill % each year. Unit 35 and 15 are great areas for deer and elk and stay out of Ntl. Forest, Hunt the surrounding BLM that boarders. But hiring a guide for mule deer is plain silly. I got a nice 4x4 in 06 during muzzleloading, there was a way bigger deer next to him but he was behind a tree so i took the next best one. Im not a "trophy" hunting, whatever has horns or the right sex is going down if i have a tag for it. But when it comes to doe's, i do get picky and prefer to take the biggest. Just gotta do your scouting for fresh tracks with lots of trails and good food and youre set. Look for private land boardering BLM that has a food plot,. set up on BLM and wait for deer to come down the mountains and towards you. Got my area for this years picked out and this time im not going to shoot the first deer i see.
