Here in coastal Georgia, we have acorns instead. Hundreds of them, hitting the roof and walls and windows like tiny gunshots every time the wind blows. Their caps crunch well underfoot, too, but they don't pile up to quite the heights that the leaves did in Indiana.
In coastal North Carolina we had giant pine cones, fallen from longleaf pines. Those were fun to collect and give to people elsewhere who could be wowed at the size.
