SAN ANTONIO - Many of us know how tough it is to start a small business. Well imagine jumping into the food business with no experience and more than seven decades later your creation is still going strong.For 92-year-old Rosemary Kowalski, Friday, November 11th marks a very special anniversary. It was on this Armistice Day in 1946 (now Veterans Day) she and her late husband Henry bought a small barbecue restaurant on North Zarzamora. That business eventually morphed into a food service company called Catering by Rosemary.
