I saw a sign saying "weapons forbidden"
I remember seeing similar signs there, and noting that the weapons in the pictures are the same ones you see at UK Border Posts as being banned from the country...
The size of the port and it being just there impressed and amazed me; between Hamburgh and Rotterdam the vast majority of imports to and exports from Europe go through there, many of the wee sea going ships are heading for Immingham and other UK ports...
Your comments on Sportsball just reminded me - when I was there in December, a friend of my brother-in-law was desperately keen to talk to me in broken English (sadly my German is almost non-existent) about Kevin Keegan of all people! After a WTF moment, I recalled from the dim-distant past that Keegan actually signed for Hamburg FC about 40 odd years ago. Very random!
I had a few football related WTF moments in Sweden and Norway as I was wearing a fleece that mentioned Dundee on it, which automatically made people want to talk to me about the 1987 UEFA cup final, Jim McLean and Scottish footballs descent in to rubbishness in general.
The area around St Pauli's ground was deserted when I was there though.
