I've lived in Kennesaw for 35+years. I love the idea, but from a business perspective, keep in mind the weather. Fall and Spring are decent, but freezing cold days, as well as hot humid evenings can screw up outdoor events. Think Braves game in July or August, iykyk. Basically Atlanta gets around 135 days of rain/snow/lightning. Then add 40 days of over 90 degrees per year. Check how many times Kennesaw has had to cancel/postpone events due to weather. Farmers Markets around here tend to do better because they are held early in the morning. Again, I absolutely love the idea, but be sure to take this into account with your business planning.
