Yesterday I rode up Chaney Trail and Mt Lowe Rd and on to Mt Wilson. First 3.5 miles (2000ft gain) are paved, but much is broken or covered in dirt. Cloud was low and wet and visibility was poor. 1/2 mile after the dirt road begins in earnest a mountain lion climbed out of the brush about 20yds ahead of me. It wandered on and didn't look back. I waited a few minutes before continuing on. I reached Mt Wilson Rd in the wind and rain and gave up on reaching the top as visibility was non-existent I headed back down with visibility down to 20ft in places. A large deer hopped out of the trees right on front of me, made me jump more than the lion and disappeared into the mist. 20 miles total. The strangest and eeriest ride I have ever done.
