tell me if you've seen this one

In a hybrid knock-off of both Dawn of the Dead and The Road, I once again found myself in a post-apocalyptic future. After all the zombies gave up and died again, we ventured out of the mall and started heading south. The street was full of people either running for their lives or running a marathon, and we joined the race. Zombie corpses littered the median and the sidewalks. Eventually we hit Florida, which was just as swampy and mosquito-infested as ever. A new hippie society had developed. It mostly involved people being naked and itchy, sitting around under the trees and letting their armpit hair grow long. My brother and I were being eaten alive (by mosquitoes, not those creepy cannibals from The Road), but then we met this random old couple with a Winnebago and a life supply of Off. Off is so wonderfully amazing. I love it. It made the shitty future at least semi-bearable.
