Was talking with an old friend last night about fishing, and come to find out this guy simply WILL NOT tie on a fly to his leader until he's at the spot he's going to fish. something about if you step into the water with a fly already tied on the fish will see it and refuse it the rest of the day.

Now I'm not at all superstitious and I think his take is hog wash but it got me curious if he's certifiable or if the rest of you have some kind of quirk along those lines when you fish?
