I keep a bag in the car that has clothes, a sleeping system, rain gear, food/water etc... I think it is important to have something like this, especially if you live in a rural area. I change contents of this bag out based on the seasons. I'm a little overdue on doing it for cold weather, so I'm taking care of that today.
Posting here to encourage others to have a "get back home bag" as they are often called.
If anyone has one and wants to share that would be cool too.
I don't have a car, but I put gloves and a hat in my backpack.
