Light on

Sometimes I can be a kid. I'm walking around target in the early morning. They have energy efficient light controllers in the freezer aisles. As you move into the aisle the sensors pick up your movement and turn t he lights on in the cases. If there were a lot of people shopping you would most likely never know this. But in the early morning they are fun. you turn into a darken aisle and the lights go on, one case at a time. If you hold still long enough, they go off. I tried to "sneak" into the aisle but the sensors are well placed. They must have had children in mind when they designed them.
