I do most backpack hunts solo, but it's not because I don't like hunting with other people. I actually love trips with people that are on the same page. I certainly don't want to be babysitting somebody, but there's nothing like being on a trip with a hunting partner that you really click with, both in hunting style and just personally. I just don't know enough people like that to be out very often. Taking time off work, traveling, drawing tags, and all of the stuff that goes into a really good trip are just too hard to coordinate with other people and all the stuff going on in our lives. If I want to hunt more than every so often, I have to go solo. Not every time, but most times. That's whether backpacking or day trips or whatever. The last big backpack hunting trip where I went with a buddy, he showed up at the trailhead after months of planning and told me he was going to have to hike out after 3 days because of work. We were supposed to be out for a week. And the problem was that we were going DEEP - 12 miles from the truck at the farthest. That makes for a long pack out if you've gotta make more than one trip getting meat and a week's worth of gear back to the truck.
I also think solo hunting is a little over hyped in this YouTube age. It's made out like you can't even hack it as a hunter if you can't go solo. I don't really buy that. There are also many things that make it great which other posters have mentioned - the quiet you can only get alone, that story about a calf elk bedding 15 yards away is amazing! And that last beer you left at the truck after a long walk back with a heavy pack alone is hard to beat.
I've also been in a few pretty ugly emergency situations in the backcountry, not while hunting and thankfully not alone. Having some company goes a long way, even if you're the one with the emergency and have to take care of that end of things yourself. Just having another person there can be very helpful if things get bad suddenly - someone to talk to or help with carrying extra weight even if they aren’t much help otherwise. Pretty easy to talk on a forum about how you don't need anybody but yourself. I've seen more than one those types in real life emergencies completely forget their training (and they had real training) and just shut down, and they weren't even the one injured, much less injured AND alone.
But, all that being said, I'll very likely be solo on my next backpack hunt. If I wait for someone else to come along, I'll probably just be waiting until next week, next month, next season. And, as many others said - the InReach makes my wife feel better.
