It was diving, so I started to time how long it was under. On average, it would go under for 6 seconds and then pop up. Soooo, every time it dived, I sprinted to the count of four and got on the ground. I did this until I got about 20 yards from him. I can't believe I got that close. I belly crawled for 5 more yards, and when he came up, I knew he spotted me, so I just let the shutter fly:) I got two good side shots and the rest was it high-tailing it out of there!
It was great fun to see how close I could get, as they are very difficult to get close to. I hope nobody was watching me:)
