Nok-Hockey (Toys R Us has the wooden one, with the wooden puck).. a ‘sandy beach area’ to play with your shovel and pail and a circular track so you could skate..with the metal skates that had the key, and fastened onto your shoes, and you could make them bigger as your feet grew, and tighten them.. Snedicker Ave. park in East New York (Bklyn) and Bradford St. park in East New York… I’d ride my little trike
