I've spent years traveling, the last five alone a couple of times per month between NY and Houston, but have never taken my hats...excepting, perhaps, one that I might have worn. What I've learned, if anything, is how to travel light and unencumbered. What do you guys do when you want to take a half dozen or so hats with you on a trip? Were I planning a trip of considerable duration, I just don't know whether I'd any longer be able to be without my lids for an extended period; yet, I can't imagine bringing six hard-shell hat boxes. Are there any secretes to transporting lids that offer space conservation and protection?
