They’re effing disgusting. I can’t even take my daughter to the North Shore in Pittsburgh because the goose crap is literally EVERYWHERE!!!! I went jogging there last summer & still have goose turds embedded in the tires of my stroller. Disgusting. And the stupid liberal tree huggers sit oo-ing & ahh-ing at them while they feed them so they can load up with more crap. Gross.
That's the reason they've become a nuisance. They've learned that humans will feed them, or that they can get food easily where there are humans, so the flocks have grown larger. Sometimes they don't even bother to migrate, because they know where their next meal is coming from.
