Today, I went for a short run through Runyon Canyon. I started at the top at the Mulholland Drive entrance, ran to the peak, then descended a little bit before turning around back to the parking lot. This ended up being a shorter run than I expected (~ 2 miles) but was still quite challenging because of how steep the trails were and how dry the air was. I had great views of downtown LA, the Hollywood sign, and Griffith Observatory. After the run the sun had set, and I walked around the observatory. They had a cloud chamber for observing particles that I could have watched all day. I was in LA to recruit new graduate students for the Bredesen Center from UCLA and Harvey Mudd.
