Both, pheasant hunting in a group is great for the comraderie, but I also have a blast just me and my dog. Deer hunt by myself or with my brother, as our hunting style is very similar
I hunt alone quite a bit, unless my hunting partner, which is my son, doesn't have school, Or if I have friends from out of state here hunting. I find solitude good for the soul, and enjoy the quietness. I have a system for when I get an elk or deer on the ground and while it works for me, it would be nice to have someone to tag along to share the load.
Prefer to hunt with a buddy, but often do alone. Either way, it's pretty much the same. With a buddy, I likely see him once in the morning and then again at the end of the day with a few radio calls in between.
It's good to know that there is someone in the general area that can help out if need be.
