Last Day in San Diego

This is the last day in San Diego. I myself bought a one-day pass for trolley and bus and visited the downtown of San Diego and the famous Pacific Beach. Since the officer of FSD told me that the security check at airports would take a very long time (to prevent terrorists from bringing explosive on board), I finished the trip very early and rushed to the San Diego airport. Luckily, I was allowed to take an earlier flight so I arrived at LA airport at about 6 hours before the scheduled departure time. To make use of every minute, I took a shuttle bus to Union Station (a railway station) and explored the nearby Olvera Street, which is a historic street with restaurants and gift shops selling Mexican food and merchandise.
