We got up early and headed to Williston, Fl, to dive the Blue Grotto, a 100 ft deep spring-fed sinkhole. We were in the second group to dive so we sweated on the dock with all of our gear on. But when we hit the 72 degree water (backwards!) it was absolutely refreshing! We got our equilibrium on a submerged platform and went through our drills. We then descended to "peace rock" at 50' deep. The grotto was dark, but looking back at the sun shining through the blue water was beautiful. Jonathan was scared to go down in the crevices, but he "manned up" and did it.
