Pay Attention to my explaination and doodling...

There are Nineteen Cows on this map.
Four of them don't have flowers.Three whites and a bull.Without those four,there are 15 cows left.I'll get to that later.
The three white cows make the main triangle.And the all meet at the bull.There for,my prediction is the aliens will land there.
Back to the 15 extra cows.There are three white cows with flowers.The also make a traingle.But in the opposite direction of the first.Like above,the meet at the bull.
Niw there are twelve cows left.Those have no used to my theory right now,so for now,my prediction for them is they will be the first to go.
Moving on to triangles of the crater...
This one is easier to see...

The cows make triangles all around this map.It actually looks a little like a spaceship.What's of that?Here in this picture,like the other,the brown cows have really no meaning.My thoughts again,they will be abducted.
THe bull in the picture is once again,the center of everything.Does the bull stand for something?Or will the aliens land in that spot?
Another prediction is that the Aliens will land on that exact triangle.
Last Prediction(Not related to maps):
The Aliens will land at the Barton Fountain.
