Geese = rats with wings.
All the MUPs around Schaumburg IL were covered in goose crap, and for that reason alone I ran fenders on all my bikes when I lived there. Motorola once had to hire a contractor to pressure-wash their entire parking lot because the goose crap was being tracked into the buildings by employees.
I was attacked a number of times by the vermin. Funniest time was when one launched off the ground head-on at me, and one of my mtn brake levers caught it right in the chest and knocked it backward out of the air.
On another occasion, one of them was safely off to the side of the MUP, but as I approached, the dumb thing made a mad dash across the MUP right in front of me, and I ran over it. It felt surprisingly firm, (like a football), and launched me into the air. Last seen, it was sitting in the pond squawking it's unhappiness.
