Tech Support: Keeping Your Tripod Dry

Question: I visited the Outer Banks in North Carolina last spring, and while clamming with my friends I saw a perfect view of the shoreline. But the water was 3 feet deep, and getting the shot required a tripod. When I return next year, I want to be prepared. Can you suggest some type of waterproofing gadget for my tripod’s legs?
