I can remember when I was young I used to love flagging the ice cream truck down. I had to do this on the street behind the one I lived on because my street was too busy to have it stop there. To this day I don't know what the blue flavor was on a red, white, & blue bomb pop but I know it was good when the cicada's were singing and the day was hot! Later on I had the strange experience of running into an ice cream truck while cutting across the Old Protestant Burying Ground (where F. Scott Fitzgerald and his wife Zelda were originally buried) in Rockville, Maryland; it had it's lights and chime going and was ready for business.
Anyway the other day I heard this thing on NPR's Fresh Aire program about this CD of songs for Ice Cream Trucks:
