"During the daytime, we would be out here working in the yard, and a car would race to the barricade, and a car would stop over there, and they would throw the drugs across, and they would be gone, so we were aware we were at the border at that time. But now that the Border Patrol is so active and the cameras are there, we are very comfortable."
“白天，我们在院子里工作，一辆车驶向路障，另一辆车停在那儿，他们将毒品扔过来，然后离开，因而，在那时我们仍意识还是在边境。但现在边境巡逻很频繁，还配有摄像机，我们感到很省心。”
