Everytime I have been back to Cologne, there have been more locks on the Hohenzollern Bridge. I wanted to add one this year and remembered it just as I was leaving for the airport so Aaron put our initials on a lock with his dremmel tool.
It's not the fanciest lock on the bridge but I like that Aaron did it himself.
The keys got tossed in the river.
See how full it's getting?
Some panels are packed full.
