On Wednesday morning, a tanker truck full of flammable liquid got into an accident in Baton Rouge, Louisiana, and Interstate 10 was shut down for the entire day.

As you might expect, traffic was a mess, and Catherine Baucom got stuck in it while on her way to work.

That was a problem, because Catherine is a surgical breast oncologist, and she was on her way to the hospital to perform surgery on a patient.

She realized she wasn't going to get there by driving, so she went to a nearby friend's house and asked if she could borrow a bike. And the only one he had belonged to his seven-year-old daughter.

Even though she's six-feet tall, Catherine put on the pink helmet, and rode the tiny bike to the hospital so she could get there in time.
