We are headed to Ky (Louisville/Lexington area) in late July/early August. Is anyone familiar with the KY State Parks system? We are looking for shaded, level spots with some privacy and kid-friendly atmosphere (i.e. swimming and playground would be nice). We think we have 3-5 days of activities in Louisville, then we'll either head over towards Lexington/Frankfurt or down towards Mammoth Cave. We'd like to get at least the first few days of reservations made for the pop-up. Any advice??
