Hello, My name is Dan Harrell and I was raised in Southwest Philadelphia. I’m 56 years old and I’m doing a paper on the game of “Box Ball” as we played it back in the 50’s.I recently had a reunion game with friends of mine of my own age . Since they no longer make the “Pimple Ball”(a little bigger and not quite as bouncy as the pink,or bubble gum colored,ball)we used what I guess you call a “Spaldeen” in New York.Maybe its because we are older but the pink ball is a shade too small for our game and a little too lively.In fact, I’m not too sure but, I believe the “Pimple Ball” was the only ball we used for our street games-I don’t recall any other ball outside an occasional “Star Ball” being used. I enjoy reading your site and wish you the best with your ‘bounce off’. Yours In Street Games Dan Harrell
