It's well worth the trouble because it is no trouble. And that area is absolutely stunning. Check with your local town hall and post office-they often do passports/passport cards. Also check with your DMV if they do enhanced driver's licenses (those that ID you as a US citizen). Not sure but I think those may be used as well.
