The Field & Stream piece is in the Feb. 2000 issue. It is in a short subjects section (can't remember the page). I agree that it seemed more like a one observation experiment than being good science. That's why I wanted to get a consensus of opinion to help figure if they might be a detriment in some situations. I do think it certainly can't hurt for us fishermen to use them only where helpful & keep the FF's on the lowest intensity setting needed. - Steve
