With support from local churchs and businesses, Corazón (www.corazon.org) is able to build houses in Tijuana and Tecate in impoverished communities.
$7,800 buys all the materials. Corazón provides the work foreman and coordination team (the "blue shirts"). Twenty or 30 people show up from the sponsoring
organization, plus 10 or 15 others who just want to help (that's me), and we build a house in a day.
