I can make fire. Multiple ways I.E. flint and steel, bow drill, and of course lighter and matches. By the way matches are the hardest for me.
Hunt with flintlock or centerfire rifle or shotgun or Bow and take care of the game when done. Honestly in a purely survival situation squirrel, turkey, rabbit type game will probably take over for bigger game like deer. Deer are time consuming to preserve and hard to move by yourself and like others said the two legged predators(humans) will be out.
With the hunting with guns, that is only as good as long as your ammo holds out. I haven't gotten into reloading so that would be my short coming. However I have alot of Black powder and Lead round balls for my flintlocks. I do 90% of my hunting with those anyway.
Gardening is a a possibility however going to the local farm supply for seeds will not be an option. So who knows how to collect seeds for next years garden? I will admit I am a tad lacking in my knowledge of wild edibles in NC. I know a few but the window for them is pretty short.
I know how to brain tan deer hides for leather if needed for clothing and I can sew well enough to make clothes. They won't be pretty but they will work. I can also make thread out of sinew. At least I've done it once.
Of course the horse stuff. I also have my EMT skills. I'm pretty good at trauma type stuff and can handle medical stuff to a point. It's hard to handle medical stuff if you don't have the meds for it though.
I'm not a prepper by any means but I do believe in being reasonably prepared for contingincies. Like losing power for a week or so and still being reasonably comfortable. I know if the grid went down for say a week bcause of an Ice storm or hurricane. My family would be warm in front of the fireplace and be able to eat.
