It was more than 15 years ago that the Humane Borders organization decided it would try to reduce the number of migrant deaths in the Arizona desert by placing water stations in the wilderness.
The group worked to get permits and insurance to place the 65-gallon drums of water on the paths migrants took when they crossed into the United States without a permit to be in the country and then walked north toward cities.
Now, one of the group's water tanks is going into a Smithsonian exhibit in New York, and advocates continue to push for reforms to the country's immigration system.
In the show:
Rev. Robin Hoover explains why he started putting water in the desert for migrants, and what steps had to be taken to gain access to public and private land. He also talks about the politics of immigration today.
