My beloved drive-in is now a Fresh Fields, a Chuch E. Cheese, and a Staples.
PF Flyers were just about the coolest shoes on the planet, before there Nike and Adidas. They outmarketed Keds and Converse back in the the day. Also, they sometimes had really cool toys that were given away with every purchase ... There was a jungle tooth thingy, the plastic tinted to look like eather ivory, with a whistle (not a regular old ball whistle, but one of those ones with the rotary blades that made a sound not unlike that of a lonely loon on a summer's evening) and helpfully provided a morse code chart so you could fail to understand the message your friend was whistling you with some authority.
Oh how I loved my PF Flyers, the ONE time I was able to convince my mom that I needed them. We were a Keds family, you see, and our regular shoe-salesman (who didn't sell PF Flyers) made a point of telling my mom how bad they would be for my feet, and how good the Keds were ....
