Now this thing is really cool! The object is to start at one end and move slowly and quietly enough to not set off the sensors. If you did, it means the birds at the other end sensed you.
Apparently kids and women did very well in the prototype testing. Men had a harder time making it through without scaring the birds. Now there's a challenge if I ever heard one! I tried it and made it, but wondered if I should admit it?
A section of the mural depicted the view of Acadia National Park from Acadia Mountain. I hiked up the mountain the previous October to get my reference. Cool place!
