How in the world would you travel 2000 miles? If you have to travel that far, chances are things have gone really bad and that means there would not be enough gas immediately.
You should never occupied any place not own or leased by you legally. Doing so classified you as intruder or raider that people on this board have trained themselves for years to destroy. I can assure you that when things are very bad, I will destroy anyone planning to invade our space illegally.
Technically, in a total collapse, the land is not "owned" anymore, if the government is gone, so no one would be invading your space "illegally".
I am not sure where you're living around the time of September 11, but most people in the country realize that it was not SHTF and bug out would have been a bad idea. People in DC greater metropolitan areas and New York didn't bug out. People in Pennsylvania also didn't bug out. I would classify bugging out during 9/11 an act treason as it was an one strike attack and your country needed you to defend the ground if it would to that.
I was too young to own a gun when 9/11 happened. I did own several knives and they were sharpened and at the ready should my country needed me. Living on campus provided an extra layer of protection from ground attack and my knives would have served me well in CQB because I knew the lay-out of the building and had the master key due to my responsibility as an RA. Any intruder would have had his head chopped off by a large and sharped Ontario bowie.
We aren't allowed anything bigger than a Swiss Army knife on my campus. What state did you live in? If you were old enough for college, you should have been old enough for at least a long gun, which you could not have had on campus anyways.
