Interesting things I have seen in Cologne.

Guards are posted around this courtyard at certain times of the day to keep people from walking on it because it could be heard in the music hall below.

Rock climbers practiced on the wall of the Hohenzollern Bridge by my hotel.

The light switches and the toilet flush button in my hotel are all huge.

I love the little cars in Cologne. Look how this Smart Car sqeezed into a tiny parking space.

Aaron should be getting his Smart Car soon. Maybe it will come with a clown on it. Hah-hah!

I couldn't figure out why there were locks attached to the fence along the bridge walkway. This one is going to bug me.
UPDATE: I have been informed that these are Love Padlocks! Love padlocks are a custom by which sweethearts affix padlocks to a fence or similar public fixture to symbolise their love.
