This is going to be a once in our lifetime Flashmob so let's do something to celebrate fun with numbers for a whopping 17 minutes and 18 seconds. GZ is a great spot for a quick gathering, signing the log book, Trade a story or two, and then just as quickly, re-disperse again. Bring your handwarmers and dress warm. Heck, we'll even take some of that time for a group photo!
If you want to you could also stick around for the day's sunset which would occur after the event is over at 15:41 This is always a great location to watch sunsets! Come prepared for the cold. You could also complete a nearby earthcache and maybe even go caching for bit afterwards. You will alway know where you were when all the numbers aligned 12,13,14,15,16,17,18
