I enjoy both. I like to actually hunt alone, and at the end of the day sit around with others, to compare notes, share stories, or just generally shoot the bull with. Some of my best memories from past hunts are from the time spent around the campfire after the days hunt.
Since I moved up here I mostly hunt alone, but only because I haven't yet met up with anyone that's on the same wavelength as I am when it comes to hunting.
The upside is, my son has his hunters safety certificate now, so I look forward to the times we can spend together afield.
