Don't Ride Your Bike on Stairs
Occurred on June 2014 / Gaspar, Santa Catarina, Brazil
Info from Licensor: "My friend and I were coming back from school on a Saturday and went to sit on the church's staircase. At that time we were both riding bikes, my friend went down the first time with his bike but didn't even come close to the bottom. The second time he fell and broke his arm in three parts. However, he is doing okay now."
