We just traveled from Oregon to Belize by car. I wanted to share some of our experiences. We crossed over into mexico at McAllen. They are currently working on it so it was somewhat confusing, but easy cross over. The roads a whole other subject. Lots of very large pot holes and speed bumps at every town. We didn't feel fearful of anything but the roads. You have to watch carefully. I understand why you don't travel at night. We had several inspection crosses and everyone was kind. No problems. We stayed in Tampico the first night at the comfort inn as they took animals. We were traveling with 1 dog and 2 cats. Very nice, very helpful people. The second night we stay in Veracruz at the indigo hotel. Very very nice. Boutique hotel caters to pets. Loved it. The next night in Villahermosa. The most amazingly, helpful people I have come across. Outstanding. Next night in chetamal at the maculis hotel. Really nice. Not typical. You may feel like this is not OK, but once you meet owners/staff it is wonderful. Its safe, give it a try. In no time in our trip did I fear the people. Its just the roads. They do get better as you go farther.
