Salzburg bridge - Locks and lovers - The Makartsteg.
This bridge had loads of locks attached to it. Like lots of bridges around the world now. It I think actually strated with a bridge in Paris. But not in Munich a bridge in the park has locks, Frankfurt Eiserner Steg has lots.
We put a lock on the cologne bridge 2011 which has absolute tons and tons of locks and we strolled down to see our lock by 354 painted on the bridge again 7th August.... it will take us a bit longer to find it if they paint over the number :D http://365project.org/bizziebeeme/out-and-about/2012-12-14
