Hasn't happened in a couple years, but I managed to hook a monster up north this weekend- myself.:madman:
I used the old fishing line trick, with a tug and pressure on the tine it came out without a snag ;)
I wish I had pics, but I just wanted to suggest that method in a post. It works. For everyone that fishes with any regularity, these things happen, and not generally in a spot where one can just zip over to the hospital. Downward pressure on the tine and a FIRM tug on the line wrapped around the hook straight backwards. Awesome.
