Hmmmm...maybe the puncture vine is only in the lowlands. I don't recall having problems with it on my tours (though I do try and lift the bike when walking across unpaved areas).
Yes, it is a "lowlands" (we are at 6,000 ft) phenomenon. It is very prevalent ON cement trails. You would have to carry your bike continuously.
