After the Mexican American War borderland residents continued to move across the borderline with limited restriction by authorities. In 1971 Friendship Park was inaugurated to celebrate binational friendship. Here families would meet and congregate without needing to pass through immigration. In the 1990s the park a fence was built. Slowly the spaces between the fences became smaller as fear of smuggling and immigrants increased in the United States. Now visitors on the U.S. side are only allowed a few hours a week.
