Last year, on our trip to Kansas, I put my pots, strikers and diaphragms in a gallon size plastic bag and wrapped them in some clothes. I put my box call in one of my boots with some socks as cushioning. The calls made it with no ill effects going out or coming back. We're heading to South Dakota the 7-12 of May and I'll probably do the same thing this time. One thing I won't do when flying, is pack my Binos and range finder in my checked baggage, those go in my carry on.
