Had a good run through Philadelphia today. It was so difficult running in the city because I had to stop nearly every 2 blocks due to cars, and the streets were so crowded that it was hard moving. Still it was great seeing all of the historic sites as I ran by. I ran to Elfreths Alley, the oldest residential street in America. Also, I ate a really good Philly cheesesteak after my run, so that was eventful.
