Thanks for this thread. I fashioned a leaf holder and put it on a friend's trailer and drove around the neighborhood scooping up leaves. I ended up doing 6 loads which amounted to approx 10 cubic yards of loose dried leaves.
All piled up and still unchopped
My gardening partner and I have since chopped them up and spread them over the 1200 sq foot of garden space. After reading this thread I've decided not to till them into my areas, but to leave them as a blanket and till them in in the spring if they still haven't broken down.
