2 people is twice as much smell sound and movement in the woods to spook game.
I have personal hunted alone 95% of the time my entire life but have also been a professional guide and hunted with or "guided" many friends and acquaintances. I prefer to be on my own, I always have a good time by myself, even when the $?!& gets deep because I know I am doing it from my own choice. But, I have seen way too many people with an overinflated sense of their abilities get in deep trouble but personally am fairly conservative yet fully competent and cognizant of my skills. I don't worry over much about my safety, accidents can happen at any time and if you are relying on someone else it is more likely to happen. That being said, I would not mind having a SPOT or something similar for the unlikely event that something did happen. I hunted in Alaska brown bear country (sometimes for bear) by myself for years and never gave it much thought, I get a laugh of people's phobias of wild animals attacking, you are much more likely to choke on your Mountain House and die than be attacked be a wild animal. A good pack is your best bet, I am rarely anywhere a cart would be useful so have not even thought of one. Mt 3x3 mulie last year was somewhere over 250# field dressed! I am a strong 6'2" ~225# and it was all I could do to drag it uphill the 200yds to the nearest point I could get the truck. Got ~120# of meat off it. If it had been farther I would have quartered it or boned it depending. I try to get it out in the biggest chunks I can because butchering it at the house wastes much less. Just my opinion, take it slow and learn as much as you can. Good luck.
I always hunted alone. Now that I can't walk much, my wife won't let me. She goes with me in case I fall. I used to get them out with a wheelbarrel. OR if it was a Island deer I just packed it out in my pocket.
