I was born in 1954 and grew up across the street from P.S. 194 in the Marine Park section of Brooklyn. Right in front of our apartment building, someone would draw the “potsy” board (never hopscotch), and we’d just start playing… Free but lots of fun! Personally, my housekey was my tool of choice. I remember my mother warning me that I would wear out the teeth on the key and I wouldn’t be able to open the door anymore… What funny memories!
