I'm loving this season so far but one thing bugs me...Alexandria, VA. I LIVE in Alexandria VA and there is not 10 square feet undeveloped and most houses are the size of a shoe box and also connected to other houses. We certainly don't have a quarry but there is a large pot hole a few blocks from me that could hold a couple walkers.
They should have taken the story a couple counties south or west to make it believable.
