First time being followed in by an 8-10 foot hammerhead

Frickin thing followed me for a solid 45 mins to an hour and was inches away numerous times. Guess he could smell the YT on the yak. Had him hooked up for a bit on a greenback as well. After being hooked he bailed. Go pro was out of juice and I was super bummed because would have had some epic footage. Oh, YT caught on fly lined green back in 100 feet of water at NW corner.
