I'm always looking for the following items:
Compact good quality binoculars.
Space blankets (The more the better)
Freeze dried food
black molle gear
black pistol belt (USGI type)
black magazine pouch
black large alice pack with frame
olive drab or black tarp
ammunition 9mm, .223, 12ga
probably more stuff I can't think of at the moment.
I am building kits for friends and family at this point.
Don't wear black web gear dude it might help you to blend in with the bad guys but the good guys will shoot you thinking your a thug. Use woodland camo or olive if you can, unless you live in the desert don't use ACU, pick the pattern that blends best in your area. Black is a very bad idea.
With food the cheapest way to get the most for the least $$ is to buy grains in 5 gal buckets or put it into the buckets yourself.
