We've made it through the first week - barely.

Tonight we're on a hill right next to the Tijuana San Ysidro border. It's a pretty weird thing to see. There's a 10ft iron wall that stretches as far as you can see. Someone on set was telling me that the wall is made of materials left over from the 1st Iraqi war. Can this be true?

As you can see here, I've been here all night. Now that it's 6AM, I'm pretty tired. I've got a flight to NY in about 6 hours. Should I sleep? Nope.
