This is part of the World Wide Flash Mob Event which is dozens of events all around the world, coordinated to happen at the same time to bring together geocachers and introduce others (newbies) to geocaching.
The schedule was as follows -
10:05 - The bubbles begin
I had no idea what the WWFM group was all about until I checked out their site. You can also find group photos from 31 different countries. Super neat !
I want to say congrats to ErikaJean for hitting 1000 that day.
Here is what she had to say.
Finally it has Happened to Me
Finally 1 - 0 - 0 - 0 Geocaches FOUND!
My 1,000th was actually an event cache. I attended the World Wide Flash Mob and we had a bubble party in the middle of a park GC3M2W4. I'm glad the event was short and sweet because you can't last long in this Arizona heat.
After the event I grabbed a multi and a traditional cache with a few other people. The caches were in the same park so luckily we didn't have to go to far... I felt like I was melting!
