About Us

Four people tabling outdoors on a street. There are trees behind them. They are smiling for the photo. On the table there is a white tablecloth with the Sierra Club Hoosier Chapter logo of black text and a green tree graphic, and a smaller blue tablecloth which says Repower Indiana with a white and yellow logo of a wind turbine and solar panels surrounded by a circle of stars. On the table there are books, petitions, stickers, and other info about the Sierra Club.
