A couple of years ago in the ealy morning , riding solo , doing my usual ride , going starting to go up Albertson's to China Flat area , I saw some huge cat tracks just as you do the sweeping left to start the climb. I didn't feel comfortable doing the slow climb by myself so I turned around and headed back to the trailhead in Simi. It must have been a big cat , if I had a camera I would have shown the comparison between my size 7 and the cat tracks. I have seen bobcats at the Simi end of this ride and they do not seem to be fazed by people , they just continue on ,that's not entirely reassuring either.
