The Steepest Street In The World Is Ridiculously Steep!

It's Baldwin Street in Dunedin, New Zealand, and it's quite steep: a 35% slope, or 19 degrees. This discovery came about as the result of a conversation I had with my son when he claimed to have gone bike riding on a road not far out of town with a 40% slope. I know we've got some steep slopes around here, but I was sure he was wrong. He was! Dad wins this round!
