Annie Welsh said she and her mother, who are from Chesterton, Indiana, were heading to an appointment Wednesday when their car hit a pothole and a tire blew out.
Lucky for them, they ended up near the District 1 police station. Eight officers and another Good Samaritan teamed up to replace the bad tire with a spare.
"We were so impressed by their instant generosity, humor, friendliness, and efficiency," Welsh said.
She plans to bring some holiday treats to the station.
