Gilbrace Ristel may be mobile, but come summertime he isn't hard to find. Ristel hails from Haiti, but for seven years he's been a nomad, roaming the often road-blocked residential streets between Federal Highway and Andrews Avenue near downtown Fort Lauderdale. Listen for the tiny tinkling of ice cream truck themes such as "The Entertainer." The music has a languid sound, like a 45 rpm record played at 33. And though Ristel can't hear this classic summer soundtrack from inside his truck, he seems to move at the same easy tempo, never rushing his young customers as they choose from prepackaged treats with names like Creamy Krunch (Ristel's favorite) and Crazy Coconut.
