"I jumped in an Uber car and said, 'By the way, Broad Street is closed,'" Sandberg said.
The driver took Sandberg down I-95 South heading to the ballpark, but missed the Packer Avenue exit. The next thing Sandberg knew he was at the airport.
"Now I'm hoping that he makes a u-turn, gets back on and goes all the way around to the east again, but he punched in something else that gave him directions," Sandberg said. "So before you know it, I was a mile west of the stadium and it was a parking lot. So I jumped out, not too happy about it, so I walked a mile."
But he still had to cross Broad Street with a steady stream of runners running to the finish line.
"It was a full crowd, full-strength runners at that point," Sandberg said. "No gaps. I talked to the policeman, 'I got to get to the stadium.' Got my briefcase and everything. He goes, 'Well, you want to risk it, kind of get with the runners and get across.' So I actually ran about 50 feet with the runners."
