About the editors of Dam Nation

Cleo Woelfle-Erskine is a lover of desert places. Co-founder of the Guerrilla Greywater Girls (now the Greywater Guerrillas) and the notorious Pollinators exchange, he prefers swimming in rivers to writing about them. Cleo is the editor of Urban Wilds: Gardeners' Stories of the Struggle for Land and Justice and author of Sink or Swim: a History of Sausal Creek, a kid's book (brilliantly illustrated by Annie Danger) that he wrote for the Oakland middle-school students that he takes on explorations of urban creeks.

Laura Allen lives in the Bay Area and is an active gardener, elementary school teacher and aspiring inventor. As well as the three R's (readin', ritin' and rithmetic), she teaches urban gardening, creek restoration, and sustainable technologies. Co-author of the notorious Guerrilla Greywater Girls Guide to Water, she has been scheming and constructing greywater systems throughout the north coast for the last six years. Her writings can be found in Urban Wilds: Gardeners' Stories of the Struggle for Land and Justice, Clamor, and Home Power magazine. Her favorite activities are smashing concrete, hanging out in wetlands, visiting people's eco toilets, and drinking tea.

July Oskar Cole learned to swim in the TVA lakes of Eastern Kentucky and Tennessee, and to identify wild plants in the forests of the Cumberland Plateau. Displaced from Appalachia, he learned most of the rest in the deserts of the U.S. Southwest: philosophy and astronomy in the Sangre de Cristo foothills, alternative building and "charco" style greywater practices in the Rio Grande bosque, and in the Basin and Range territory more things than can be listed. His work has been published in ColorLines magazine and the 2006 Best Gay Erotica anthology.

Annie Danger (illustrator) lives and works in the San Francisco Bay Area. She is, among many things, an environmental illustrator, a guerrilla greywater girl, a tattoo artist, a financial manager, a dirty, dirty transsexual, and a fighter/lover (it's all about the passion). She is honored to be published. Annie welcomes commentary, requests, and queries at hylotropictattoos@yahoo.com.
