If money was no options, then for Rocky Mountain Mule Deer, I'd probably go to Alberta Canada. If I wanted a desert Mule Deer, I'd go to Sonora Mexico. If I was really lucky in the draw, I'd go to Utah or Arizona. I would avoid public land with vehicle or ATV access. It's hit or miss, and anywhere you go, somebody else has already put in ten years or more hunting it and knows it better then you do.
If money is a concern, and you have a lot of time, deep into a Wilderness area. The more points needed, the better the area usually is. For those types of hunts, it doesn't matter so much what state you go to, you put in for every state and go to the one you get drawn.
If you want to see a lot of mule deer, and you are willing to pay for it on a guided hunt on private land, Easter Montana is amazing. When I hunted out of Broadus, I shot the 92nd legal buck that I had seen on the third day. I saw bigger then what I shot, and I regret not going after one of them that I video taped, but didn't realize what he was while looking through the view finder. That one haunts me and always will!!! Easily 30 inches, and deep forks. Mine was 28 inches and just a nice clean, older buck. My buddy shot one that was not quite a wide, but had more points. Two other guys in camp shot bigger. One on the day I did, the other on thee last day. Four other guys shot theirs too soon and didn't believe their guides when told not to shoot. They where the biggest bucks they had ever seen, and the fever took over.
That was 15 years ago, so things might have changed. But if I was going to book a mule deer hunt, that's where I would start.
