Whoa. Quite a fantastic story. Quite a tremendous recovery. Keep on keeping on.
And keep your faith in humanity-- it is possible that no one saw the accident and the immediate afternmath because of the bulk of the 18-wheeler blocking the view. Be blessed that someone called in the bike laying on the roadside and especially the officer who did more than just a driveby on that report.
Stay in touch, and good luck.
