Normally alone. I did hunt openiong day with an acquaintance this year. Sometimes it's nice to have a companion. didn't see a thing, though.
Nice caveat to the story is that my companion was after his first deer and was all worried about how to field dress. I told him to give me a call if he got one and I'd come out and help him. Sure enough, about sunset the next day, I get a phone call and an excited voice shouts "I got an eight an point buck!"--I could barely understand what he said, he was so pumped.
Went out and discovered a very happy dude with a big-bodied eight pointer with about a 130 class rack. Perfect symmetry and excellent mass. A very eye-appealing
set of antlers. I walked him through the field dressing, loaded him up, and that was that.
It was really cool getting to be a part of that man's experience.
