I think the .22 rifle is a good choice for a survival tool (espicially if you are using a suppresor). I wouldn’t want to use it as a primary for self defense against 2 legged wolves or anything bigger.
Miss Hannah, Have you scouted your route? Think about the swampy areas, I know winters here in the coastal region are mild, but hypothermia can be an issue. Cottonmouths are a bigger issue in warm months and I would recommend a very good bug repellent (unscented if you can find one). I am only bringing these up cause most of the folks I know live in town where they spray, out away from those areas it can be bad.
