A peaceful section of the Rio Grand River is viewed from a one-lane dirt road. Across the river is Mexico. Around the bend came our surprise. There were several pickup trucks blocking the road and rowboats on the river bank, with men loading the trucks. They appeared surprised to see us, and we felt the same about them. They ran to the far side of the front truck and ducked down. I put our truck into reserve gear and went as fast as we could go backward. Time to go home.
