A border wall is definitely needed and is definitely effective. I live in El Paso and on Wednesday when I was driving my daughter to school along the Border Hwy., exactly where the border fencing ended, the Border Patrol (with 6 or 7 vehicles) had rounded up 100 + illegal aliens. I'm sure they have been released into the US population by now. That fence/wall needs to be extended along as much of our Southern border as possible. Walls work as evidenced by the wetbacks crossing where the fence ended, not along any part of the border here in EP that has a barrier.

l told my pap and mam I was going to be a mountain man; acted like they was gut-shot. Make your life go here. Here's where the peoples is. Mother Gue, I says, the Rocky Mountains is the marrow of the world, and by God, I was right.
