PROBLEM: San Diego (CNN) Twenty-five years ago, Paula Claussen's friend invited her to make the short trip from her home in San Diego, California, across the border to Tijuana, Mexico, to donate clothing to people in need. Claussen didn't expect that day to change the course of her life. The drive took less than an hour, but when they arrived at their destination -- a shantytown on the outskirts of Tijuana -- Claussen couldn't believe her eyes. "I was shocked by the conditions that I saw down there," she said. Families with young children were living in ramshackle homes: The dirt floors turned to mud when it rained. The walls had gaps, allowing tarantulas, rattlesnakes and rats to invade. Many roofs were merely old tarps with holes in them.Paula Claussen visited Tijuana, Mexico, to donate clothing 25 years agoThe poverty she saw inspired her to come back and build better homes for residentsProject Mercy houses replace shacks that often have dirt floors and lack basic amenities
