A Mass Migration

Today I rode in a vehicle down to Austin from Norman in a little 4-kicker with two bikes strapped to the back with a friend of mine. It was less than scenic, yet I cannot but help to mention a phenomenon I noticed while traveling the nation's main vein, I-35. About two hours North of Austin's first exit I began to notice, and so did my wonderful companion, that every vehicle was either an S.U.V, or large truck loaded with tons of shit in a very haphazard manner, and we were the only "car" on the road. Upon further inspection we soon learned that all of the license plates belonged to states from the south and northeast portion of the United States. Also, that the occupants of these vehicles carrying the content's of homes were driven by generally overweight, Hispanic, or country lookin' folk. So why is it that they all seemed to be going to Austin, or at least south Texas? They say (in the magazines and on polls), that Austin is the number one growing state in America... are they all moving here? Is it migratory workers moving further south due to cold weather, and the lack of available work due to the bankruptcies and economic troubles that have befallen this nation? Or perhaps, and this is the best theory of all in my humble opinion, is there a mass outbreak of zombies in Canada that has quickly spread to the north east, and south east parts of North America? That would at least explain the terrible job of packing these people exhibited. All in all, we know one thing, they most likely were not simply going to visit family, they all had far too much shit for that. If you have any theories of your own, or would like to embellish ours, please feel free.
