There is a Target right next to a Petco in my area. The parking lots touch each other, not even a grass median between them. But they put up a tall fence between them so there is no way to go from one store to the other without driving out of the parking lot of one, onto a main street, and then turning into the other parking lot. And if you go to Target first, you have to turn left onto a street that has a median and have to go do a U Turn farther down the street to get to Petco.
