I read an article recently in a local (Cali) publication about the revitalization and restoration of the 51-mile LA River. Pocket parks, bike paths, eco tours, clean-up/maintainance, art, murals, new fencing, wetlands, native gardens and on and on and on. It is inspiring to read about the local and state agency efforts and FoLAR's (non-profit "Friends of the LA River")
The ecosystems along the river are all very different, so each stretch in each community is different. I enjoy most looking at the pictures.
