There was a thread on this a while back. I really don't understand what the difference is really. I mean I do enjoy a camp with friends. Just got back from Missouri hunting with friends that live there. Of course the were rifle hunters and I had my bows.
Realistically when one leaves camp, wanders in, climbs into the blind or tree stand, they are generally alone.
Yes, there are exceptions. Sitting in a blind with a guest, youngster or new hunter to "guide" them. Or where you are required to have a guide or PH with you by regulation.
But even at our ranch, we are all bowhunting although I'm the only trad shooter, but we sit alone.
Even when I'm there alone I'm never really alone. I get messages and texts. I send pics to buddies and discuss why we dislike a politician or work. Heck customers will text or call you any day of the week or any time of the day.
I do enjoy being there alone. There are safety considerations. Especially after a few heat attacks and stents I'm expected to touch base with my wife. But I can nap when I like, eat what and if I decide to sit a morning or evening hunt out, it's okay.
So I guess all that was just to ask the question, what really do you mean by "solo"?
