aww, nuts

[boblothrope.livejournal.com]

Someone I know has a reserved parking space that's under a mature walnut tree. He had some damage to his car last fall from falling nuts (lots of dents and a broken sunroof).

He's gotten an estimate from an arborist to trim the tree, but it probably wouldn't help. The tree is so tall that the nuts could still reach the parking space even from the furthest part of the tree.

I assume this problem has occurred a lot in New England. Does anyone have any ideas, short of cutting down the tree or building a garage?
