know for budget reasons they can’t have zombie hordes in every scene but there are 300 million Americans give or take - you would expect to see them all over the place but we only get one or two shambling zombies here or there.

this part doesn’t bother me… we’ve seen each of our living characters put down dozens of walkers, and some of the early-days flashbacks suggest lots were bombed into smithereens or trapped under rubble — no more than 1-2% of the population could possibly remain.
