Mike- very informative site particularly on the retrieves. You may be interested to know that it seems that HABATAT Mureels can be taken on a plane in carry on bags. I flew to Georgia for Christmas and wasn't thinking and I had those plugs in a box as a present to myself with a sticker on it that said "to Rob from Habs and Tattoo". When I put my bag on the belt I said to myself that they will never let these plugs on the plane. But they went right through- but the poor lady next to me was stopped for having a nail clipper. I think Mureels with those hooks could do a lot more damage than a nail clipper. I would not recommend trying it again. Good Luck Mike. Keep up the good work.
