Since the Micron thread has morphed into trips down memory lane, here is mine about Northern Lights. Acme groceries was located at one end of the plaza. Our one car family would shop there early Friday evening for a week's worth of groceries - two carts full. After the grocery shopping we parked the carts on the sidewalk outside of Acme and then visited other stores in the plaza, Chappell's, the S&H Greenstamp store, etc. We then would retrieve our groceries from in front of Acme, load them in the car, and then make the weekly visit to my grandmother. Never worried about having anything stolen from our shopping carts. Early 1960's.
