Out of gas .

It's a long way from energy town Houston, Texas to the dry rainforests of eastern Bolivia. Yet the political heat generated by two government investigations of failed U.S. energy trader Enron is blasting through the Bolivian jungle just the same, like the 628-kilometer gas pipeline Enron built here with taxpayer support. Critics charge that the bankrupt former energy giant ran roughshod over the environment and the rights of indigenous peoples when it built a pipeline from the Bolivian city of Santa Cruz to the Cuiaba thermal power plant in Brazil's Mato Grosso state. Indigenous groups are waiting for the collapsed energy giant to deliver land promised them for cooperating with the project.
