I always keep a "Get Home Bag" in my car (now 4R). With all the terrible weather its good to be prepared at all times. I made it my self since a lot of prepackaged kits don't have the quality or some of the fine details.
In my 5.11 backpack:
- Change of hiking cloths
- Hiking boots and extra socks (wool)
- Food MRE and freeze dried
- 1 Gallon of water (multiple bottles one out of mettle for boiling water)
- Tarp & rope
- Thermal blanket
- flashlights, batteries, knives
- Full trauma kit (not just first aid)
- Lighter/matches
- Water purification drops & Sawyer water filter
- Rain coat
- TP
- Compass
- Bug spray sun lotion
- Bolt cutters/Lock Picks (don't ask LOL)
- I'm sure i forgot a few things
All but the water bottles and boots are in/on my 5.11 backpack:
