The snow geese are back in full. From a distance their flocks look like snow banks. With flocks this large, streams of geese fly in and fly off nonstop. You can watch them for hours and never see them crash into each other.

How do they do that? Fly so close their wingtips practically touch but never collide? Imagine riding in a jet and coming into a landing with hundreds of other jets just feet away and all landing without bumping into each other. That would be a plane ride that would take your breath away.
