The first year we had our MH, we were at Big Bend in TX. I found out just before we departed from home that our Passport had expired. So that left us out from going to Mexico. While at Big Bend I asked one of the BP guys about going to Mexico, explaining my passport issue. He told me, "being a US citizen, we would not keep you out of the US, however, it could take a little longer to get back." Did we go to Mexico on that trip? No way! But we had our passport renewed since then and have been to Mexico. In the long run, get you proper papers that you need to travel. Happy traveling. Gary
