Several things caused a pause after watching this last episode. That vast dumping ground, most of it from the time before the fall, would be a festering, smoking ,stinking pile of decaying matter by the time Rick and gang got to it. I get the feeling it would be almost intolerable to hang out there for any length of time, unless of course one had no sense of smell. The idea that there are pathways through huge piles of trash to get to the top of the heap seems a bit of a design challenge . The skinny head girl, just casually pushing Rick off of his feet, down the pile. That is in truth not an easy thing to do to a balanced somewhat strong man, though that is giving credit to Rick, who has not been so as of late. I did like zombie spike man, that was a cool visual. Rick better get a tetanus shot after that encounter, he is going to need it.
