I'm smack dab in the middle between 2 stores, both ~4 miles away.
I haven't noticed a stench but there's almost always some nastiness in the dairy cooler, dried egg or milk or whatever on the floor. It is, not surprisingly, the worst during the busy holiday season.
There's often some litter outside the store, but not real bad. My sidekick once found a $20 bill that had blown up against the outside of the building.
