There is a bunch of good advice here in this thread.
One of the best bits of advice that i could give you is to find other people who are like minded, and also have good skills. I already know who i would want to be with in case of SHTF, and i have made sure that my skills make them want me to be with them too. Do you have any friends that shoot? Hunt? Fish? Any Doctors? If so, those are the people that you should make a plan with.
Also, are you married? Any kids? Realize that even if you are capable of survival, and capable of hiking 12 miles a day with 70 lbs of gear, your wife/gf/kids might not be able to.
Its good that you are putting thought into this process, but i would also seriously consider staying put if SHTF. There are many good reasons why staying in can be safer than being on the move.
--You know your area better than you know some forest 500 miles away.
--You may not have enough gas to get to your bug-out-location
--You might be injured, and moving could be very hazerdous.
--You can keep more supplies at your home than you could take with you.
--Everyone and their dog will be trying to bug out, and (1) there is likely to be a massive traffic jam out of town and (2) there will be massive crowds competing for food, water and land, and (3) the people who live in that area might not be too friendly about sharing their resources, and they will know their environment better than you will.
My recommendation would be to make a plan to stay where you are. Have food and water, medical supplies, waterpurification, and other disaster supplies.
In my opinion, bugging out should be a last resort, only if your home is uninhabitable.
With that said, it is a very good idea to have a small bugout kit available if you do need to run.
