The park (or Queen perhaps?) employs a couple of leaf-blowers to blow all of the leaves into long lines and piles for a tractor with some sort of combine harvester (I think that's what it says on the side of it) to pick up. Lucky for us (and unlucky for them) are the days when we get to the piles before the tractor!
Freddie loves running through the piles, inspecting individual leaves and throwing them in the air. It's definitely an activity that reminds me of my childhood (we used to go door to door and ask our neighbors if we could bring their leaves to our yard to make our mound bigger) and the best part is- we didn't even have to rake them up!
