Free Hugs in Kobenhavn and Amsterdam

I have given two "free hugs" in my lifetime, both in major European cities (the only two major European cities I have been to). I hope that this becomes a trend, and that I am able to give one in Leeds, one in Geneva, one in London... and anywhere else I go that's considered a major European city. I would like that.
(Note: these have happened entirely by chance. the first time was just a girl walking down the street, holding the sign. i went way out of my way to hug her. the second time, in amsterdam, was a group of people. might have been a demonstration. either way, i just stumbled upon them and have therefore hugged complete strangers in completely strange cities.)
