I can recall doing a lot of things many of the people posted. Running an errand to Zickerman's hardware store for my father to pick up nails. (It all sorts of ladders leading to lofts, etc.) Picking up prescriptions at Marder's. Going to Stanley's for school supplies (including this funny looking clay that came in rectangular blocks) and Spalding balls. Seeing Conquest of the Planet of the Apes at the Laurelton theater. (The icon is from the movie.) It's interesting that in the movie describing the making of the Planet of the Apes movies, one of the producers tells how in one showing in the Los Angeles area to a predominantly African-American audience, practically the whole theater was cheering for the apes to kill the humans. Same thing happened in my neighborhood theater.
BTW, Noah and Vanessa, do either of you remember a Mr. Rabinowitz who I think taught history at Stuy for a while? He lived across the street from me.
