I do not really know how events are organized here in the UK but I'll try and mimick what we do back in Spain.
The idea would be to meet next to that nice ship by 19:00 and stay for thirty minutes (until 19:30) exchanging TBs, stories and funny adventures. I would also love to get some more information about what I am about to face, trying to find as many caches in London as I am able to in the yet-to-be-defined time that I'll be staying around. Where should I start? What should I avoid? What are the common courtesies around?
Hope to see you all around!
