Unless it is in the middle of no where and chances of zombies mass there are slim.
just a few hill Billy zombie stragglers
It depends on the zombie type whether there will be mobs.
If they are the kind that can follow the behavior of the zombies around them(dawn of the dead, the mob gathering outside the mall because others were), or the type that follow what the rest of the zombies are doing only if it is because they were exposed to the same stimulus to create that behavior(High School of The Dead, zombies all rushing to a sound if they herd the sound).
I did think of the food problem when I saw the picture too. But the first thing that popped into my head as a possible solution was little more that smart zombies trying to kill the food before eating it(cannibals)
