Flint expatriates seem determined to spread Coney Islands across the country, even Martinsburg, West Virginia:
"We grew up in Flint, Michigan (in what we believed was the center of the universe) during the 1950's and 60's. Scattered throughout our universe were a number of Greek restaurants (coney islands) serving a quality frankfurter, topped with a "special dry meat sauce" (brought to this country by Greek immigrants in the 1920's) and garnished with yellow mustard and sweet onions. We considered this the greatest hot dog known to man - the, so called, Flint Coney Island. Patrons from all spectrums of life sat side-by-side enjoying this delicious preparation, along with local soda "pops" such as Vernors and Squirt, and continue to do so in modern day Flint.
We both transferred to Martinsburg with our employer in 1969 and instantly fell in love with Martinsburg and it's people and now concede that center of the universe may not yet be decided. However, one fact remains constant in our memories. The Flint Coney Island is the best hot dog we've ever tasted. We have shared a common dream since 1969 . . . to bring the Flint Coney and some of our favorite soft drinks to our friends in the tri-state area to enjoy. And now, for your pleasure, we present SIG'S CLASSIC CONEY ISLAND LLC and in all its glory, our original FLINT CONEY ISLAND. In our common dream a voice reassures us to "serve them and . . . they come come".
