Aluminum bottles were developed so that folks coud get the glass bottle experience at the race tracks, without the dangers of broken glass. (Race tracks don't allow glass bottles).
Any pictures of the Great Mills road area from back in the day?
I'm also looking for pictures of the Kings 5&10 Dept Store (corner of Shangri La and 235), Nav Air Grill (just outside gate 2 on Great Mills Road), and anything else related to the Lexington Park area.
