As I was heading west out of Joliet, IAIS train SIBI rolled into Joliet. I turned around and headed into Mokena, IL to try to catch it. The hill slowed him a bit and gave me time to catch him. No tripod was used, so it is shaky.
And as I was about to turn onto Interstate 380 to go home, guess who I seen. BICB was passing Hawkeye.....and so I made a dash to Oxford. 508 leading, 513 was second out.
