Anyone here seen
Night of the Comet? It's pretty much the same premise.
I've often pondered this myself. I guess I'd travel around the continent and see everything I could. I don't expect my life would last too long as eventually food everywhere would spoil and seeing as how I cannot hunt or forage I'd be a goner for sure. But it'd be a kick until then. A lonely one, for sure, but I'd live it up as best I could.
