Attached are some photos I took of Cypress Springs in Vernon, Florida. It's sorta' difficult to find it (unless you're in a boat). I happened to use Google Maps to track it down though. These were taken about 1,000 feet from me (I had to fly over "private property" to get there), and I didn't bring the it lower than about 250 feet (I was afraid of crashing my drone).
Either way - enjoy!
Photos of Cypress Springs in Vernon, Florida. This location wasn't easy to find, but after doing a bit of research, I discovered an area where I could take off and return to land, and managed to be within half a mile of these springs.
