Interesting article about biking along the LA River. It shows all the different challenges and the current condition of the LA Pedestrian Bike Path. Here is an excerpt:
I finally arrive at Griffith Park and the start of the Glendale Narrows bike path, which will take me all the way to Chinatown.
This is the second soft-bottom section, and probably the most popular part of the river. It runs through Atwater and Frog Town. Lots of cyclists going way too fast. Some will be unnerved by biking no more than 20 feet from the bombastic 5 freeway, but I’ve always loved it. There are tons of birds. The water — from a treatment plant — seems to shimmer.
