I am kind of surprised to hear the "laminate them" recommendation. I figured that maps are heavy enough without laminating them and on a long-ish US tour there will likely be a 10 more state maps to carry. Also laminated maps don't fold well with the lamination materials that I have seen and I have to wonder how you laminate a large map like the Texas state map.

So I am curious. Do you just laminate smaller map sections? Do you have some thinner, lighter, more flexible stuff to laminate with? Probably kind of moot for me since I've never had a map not last long enough to cross a state, but I am curious.
