We are 2 couples + one visiting London, this is the one day all of us are located in London together and we would be happy to meet up with other geocachers...
So what about having a meet and greet with us at Hyde Park? We are quite friendly, not much left of the old viking blod. We might be a bit cold, we might even talk english a bit funny.
So we where thinking about meeting up at 11am and try to have a chat with everyone for about an hour or so. The event will officially end 12pm.
We will be standing there with our gps, phones and look kinda lost.
Look for the people holding a trackable code 
Fun fact: Did you know that one of the Earth caches in Hyde Park is created by a Norwegian?
