From WalkSF:
Join Walk SF’s Elizabeth Stampe and Nature in the City’s Amber Hasselbring for a tour of Civic Center, the Tenderloin, and the habitat these neighborhoods provide for butterflies and people alike. We’ll learn about our local swallowtails, discuss opportunities for improving walking conditions and greening local streets and parks, and end up at a delightful and unlikely oasis: the Tenderloin National Forest.
