I just found out about the geocaching World Wide Flash Mob happening November 10th all over the world. There are 28 entries so far from countries such as the United States, Canada, South Africa, Iraq and the United Kingdom. I can't believe there isn't a post here about it so I wanted to get the word out more so more cities will participate. Check out

for some of the details. To see a list of participating cities do a search for caches using keyword 'WWFM'
I'll be participating in the London WWFM!
Hope to see you all participate!
