Rock Sandwich restriction in Jug Hole (Blue Hole Spring, Ichetucknee River)

The Rock Sandwich restriction in the water source tunnel at Jug Hole. Before you tell me, I know I didn't need to take tanks off. At the time I didn't know and it seemed like a good idea. Video by Teddy Garlic with Gopro Hero 4 and two Big Blue 10,000 lumen video lights.
