We have a ton of them on the entire MUP, which follows the river through town. Often I see parents (I'm assuming who aren't from around here) encouraging children to "go pet the tame birds here in the park." Never ends well.

Also, a poster above mentioned the possibility of dispersing them with an air horn. I've blasted them with my AirZound when there's been a whole flock of them standing in the path. Doesn't even phase them. All they do is turn to face me and start hissing. Apparently they're aware of the Stand Your Ground laws.

One of the funniest things I've seen one day on my commute to work was a guy running in the opposite direction at top speed. He came around the corner, saw me and screamed, "Geeeeeeeeeesssssssseeee!" Not far behind from around the corner came a whole flock of geese that had taken after him. I'm not sure what he did to anger them, but they weren't happy. As they went by me in hot pursuit I nearly fell off my bike from laughing.
