That's a great story, and one I can definitely relate to. My Dad and I used to bait fish for carp a lot many years ago, and landed a menagerie of snappers. Breaking your line is the best approach. One time, we tried to remove the hook from the turtle's mouth with a stick and the stick was bit in half! They are nasty creatures. Turtles must be on the move, because last week I was in Maine and I also saw a giant one in a stream walking around amongst a few small trout. Thanks for the report from MA.
