Check Your Knots

Have you ever hooked a fish, I mean a good fish, only to have your line apparently break just when you were about to land him? I have, and it is one of the most frustrating events a fisherman can experience. Most of the time when this happens, if you look at the end of the line carefully, you will find the line really did not break. Rather the knot came undone! And when you realize that fact, you become even more frustrated. How many knots do you know how to tie?
