“Is this a taxi?” That’s the question that launched Abbott’s Limousine and Livery Service back in 1965. Don Abbott had recently lost his leg in a construction accident, and was looking for a way to provide for his growing family. He had gone down to the town park to people-watch and think about his options. When a visitor to the Berkshires stepped off the Greyhound bus and asked Abbott if his car was a taxi, he recognized an opportunity. “He came right home to discuss it with our mother, and they went down the next day to register our car with the town,” says Paul Abbott, Don’s son.
