......on tv right now...imagine that:being an entree' for a Great White Shark...THAT is at least one thing us in the fresh water areas of the country dont need to worry about...Although,I HAVE heard stories of giant fish lurking at the bottom of our Great Lakes and the surrounding waters....imagine being out in neck-deep water detecting-ya look down into the water with yer mask on...and coming face to face with a 7 foot sturgeon!!I once had a school of large mouth bass checking me out -They were hanging out over the drop-off in deep water-they didnt look like they were interested in considering me as a snack,though....
