First of all, I gotta say i am not a big fan of the "bugging out" idea at all. Better, I think, to live in your bugout location full time and be done with it. If you are willing to consider this, the first 2 factors to consider are population density and climate.
If you live in a congested area, no amount of prepping will be enough to get your through a prolonged SHTF scenario. Yeah, you might increase your odds of survival from .001% to 1%, but that's not gonna cut it. This basically comes down to population density vs the ability of the land to provide food. Long term, it's just that simple. If your plan is to basically Rambo your way out of the city, travel miles to some safe haven in the nearby woods and then assault it if already occupied (ooops) or defend it against throngs of starving people, you are planning to die.
Climate is another major factor to consider. Yes, you might be able to squeak out an existence in Alaska or wherever, but why make it harder than it needs to be? You wanna spend 10 hours a day chopping the wood you need to make it through the winter? I don't. I would suggest you look for land in USDA plant hardiness zone 7 or above.
So, for me, the ideal general location would be fairly close to a small farm community which can produce far more food than it can eat, but is about 50 miles from any major population areas. Such a community will tend to band together in hard times, probably forming a local militia in order to patrol and defend their community. In small towns, everyone knows everyone, and these bonds would carry over to a survival situation. A small community will also have doctors, dentists, and other specialists you will probably need. And, do you think farmer Joe is gonna shoot a neighbor over a few bushels of wheat when he has 100,000 bushels rotting in his silos?
The next thing to consider is water. Spring water is the best because you don't have to pump it. City water will be unreliable, and water in deep wells might be impossible to get to if you can't pump it out. A small pond is a good idea if practical, and you should still store as much as you can in jugs or barrels. Since water is so critical to survival, you should have multiple sources and some way to make ANY water fit to drink.
So, be in a good location with some food and water stored, have good relations with your neighbors, and forget about bugging out. Instead, pick your spot carefully and make a stand.
