Dude i posted the EXACT same thing a while back.

Anyways my plan would be to FIRST steal a bunch of trucks w/ flatbeds, then get weapons then just fill up the trucks at a local walmart, walgreens warehouse etc. With a few chainsaws u can head to a forest area and build an encampment within a few days then you start growing your own food. Basically regress into a survival mode which would suck entertainment wise...but i have to say there would be one last stop on my way outta town and that would be: My dealers house hahahah!!!
