I posted the photo of the compass yesterday and here are the wheels with the compasses on top that control the little boats in the pond at the Wild Animal Park.
I will admit that I have tried this before myself, but only once. I had great difficulty controlling my boat and I confess I did not use the compass.
And I also admit that I was successful in ramming Mrs. Amoxtli's boat, but only a little bit.
As there are ten wheels and little boats in total, I am now thinking of having our photo group do a demolition derby of sorts during our December Photo Shoot.
I will not participate, but will photograph them as they attempt to navigate. I will then post the photos in this exciting gallery: Photo Friends
Don't tell them ok?
