In this northern Florida diving adventure, Jonathan teams up with cave diver Wayne Kinard and explores Ichetucknee Spring, otherwise known as “Jug Hole” in Fort White, Florida. This is Jonathan’s first real cave dive in Florida, and he learns how these caves are different from the caves in the Yucatan and Bahamas. It’s an epic cave diving adventure!
