Crow is on it hard. Knowing your AO is huge! Get USGS maps from the local college, they Xerox them cheap. Get them printed in plastic paper at the REI. Walk off the routes till you know them by heart. Meet your neighbors. Let them see you moving around the area.
Get FIT!! Do it now for free. Quit being such a lazy pussy, it will cost you your life and your families lives as well. DON'T BE A GEAR DONOR.
Use the skills you will need post collapse, make fire with friction (it is fucking hard), purify water, cook on a wood stove, cut wood with a hand saw and learn the fault's inherent in these systems. I found out a good one a couple of days ago. My 5 gallon Blitz gas can will not put gas in my pickup truck.. the neck is too short. Would have been pretty fucking stupid to have found that out later and would have really made me look like a chump.
If you take one piece of advise I'm giving it should be "quit being a pussy," every single one of us has the ability to become PT Gods all it takes it the commitment to the cause. Remember that John Kennedy said "We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one which we intend to win, and the others, too."
Think about that while you are running it will last you a while!
