Sounds like Tim had one the worst days you can have on a bike ride.

He was lifeflighted to Memorial Hermann hospital after being found
unconscious and the word is that it may take about three weeks to
totally recover! He does not have any broken bones or major swelling
and his last catscan did not indicate any bleeding on the brain. He
is at home now but it may still be a little while before he will be
able to recieve visitors. He will probably be checking in on this
page.

Wish you a speedy recovery Tim!!!!
