What is a person to do?
Say you have a farm which is located near or at the border with Mexico.
You wake up one morning and find several hundred people camping on you farm.
What are you to do?
Are you OK with them eating your crops, using your land as a bathroom, or maybe some looking at your house for whatever reason?
Obviously you can't invite them in for a quick meal or offer a nice bed for the night.
So how would you feel if that happened to you?
