What’s a mountain? Florida is so flat I can stand up and see Georgia
Hmm...well, OK, then, I guess my advice to carry snowshoes all year is right out...
I also keep:
A fully charged high end Lithium-Ion battery jump starter (can start diesel trucks if need be)
A tire plug kit (High end air compressor that clamps on to the battery as well)
CS gas with pepper spray at instant reach.
OBDII reader and multimeter in the very full tool kit.
Canned high protein drinks (48 grams).
