1. Grand Trunk packable down blanket. The thing looks ridiculous, it's thin and small and packs down to nothing. I didn't believe how warm it turned out to be.
2. Fleece hoodie. Kept the back of the neck and the head warm.
3. Cheap fleece skullcap. I think I got it for three bucks at Home Depot.
4. Wool socks. You don't want to sleep in your shoes if you can help it - they tend to restrict circulation just enough to make you cold.
5. Wool gloves. Not tight - same thing about circulation.
6. Sterno stove with a tin cup. Because coffee.
7. Instant coffee. Instant chocolate. OhmyGodthatwasgood!
8. Beef jerky. Foil packets of tuna.
9. Water.
10. A little airline-size pillow. Silly luxury but it was nice.
11. Toothbrush, toothpaste, mini-bottle of mouthwash and a hairbrush. I felt great when the cops finally showed up.
12. Cheap LED flashlights. I had at least three.
13. Battery charger for the cellphone. Finally found a working outlet at the rest stop the next day. In the meantime,
14. Lifecharge power bank for the cellphone. I didn't turn the phone off when I found no bars, and it ran itself dry seeking a signal. Dumb.
15. A change of underwear with clean socks.
16. A little Charter Arms .38 snubbie with 30 rounds of ammo. The only thing on this list I didn't use, although just having it was using it.
There was, and should be more, of course, but that's what of what I had that I ended up using. YMMV.
Thanks for the ideas. Hubby is driving cross-country and back next month. I will put a kit together for him, adding to our BOBs especially for the winter weather.
