It wasn't the map is too small, it's the junk pile

It doesn't exactly feel like a post-apocalyptic world. In a post-apocalyptic world I don't think I'd be running into people every hundred feet. Apocalypses tend to have drastic people-reducing tendencies, unless, of course, we're talking about one of those fruity religious apocalypses, in which case TV sensation Kirk Cameron is probably lurking about here somewhere.

Seeing how there's 500-1000 people (my assumption). I don't think you can consider that "a lot".
