Hyup to that!
I was very proficient at map reading and coordinates and used those abilities many time with LT in the middle of the jungle numerous times.
For the car:
Also, just buy a small size ATLAS. I carry one in the Net pocket on the back of the driver seat and that is its home. Even though I have GPS on my phone, on my Car's screen, plus a nice large Garmin with free lifetime map updates, I am never without directions but a MAP is often the best way to know exactly where in the heck you are.
I suggest NUTS, TRAILMIX, Protein or Granola bars for food. I keep several in my glove box all year round...
A Good blanket, flashlight, spare batteries, battery operated lantern are good choices to have in car also.
I also CARRY, as in having a weapon for which I am properly licensed to carry.
XTRA insulating SOCKS are a good idea also to keep yer feet from frostbite in severe cold...
Just some thoughts. I have to go now to a client...
Be back later...
