Lester Wood, 70, alleges that "The Day After Tomorrow" star gave him permission to ride a trial on the Pacific Palisades property in Los Angeles, but he was thrown from his mount after the animal was spooked by a sprinkler system, reported TMZ online.
Wood spent nearly two months in hospital after suffering injuries including concussion, broken ribs, a shattered pelvis and internal bleeding, and racked up nearly USD 500,000 in medical bills.
He has now filed suit against Quaid, who no longer owns the property, claiming the trail design was flawed.
