I discovered the plank with 2 other scurvy dogs and a nice geocacher volunteer lady who was taking tickets in area 51 at the 2014 Geobash. Apparently the plank can only be walked by 4 people at a time and since we were short one spot, the nice volunteer lady volunteered to walk the plank with us. Amazing that this classic hasn't been discovered for 3 years. But it was a lot of fun just the same. Thanks for bringing this to area 51 and the Geobash event.
