Damn! One of those "oranges" drop on your haid and you're gonna have a bad time
When they start coming down, I try to go out every. Single. Day. and pick up a bucket, maybe two. If you leave them on the lawn more than a couple days, the hulls go black and sticky. If I wait to just "do it all" on the weekend, I'll be in traction because it'll take hours to pick up the yard, and the trees will still drop more. I have come very, very close to getting beaned. Windy days are a distinct no no for gathering.
And nothing wakes you in the middle of the night like a one pound
walnut dropping 50 feet onto your metal basement hatchway doors, or the poor, severely dimpled now, Weber grill, or the roof.
