Quick Update
Made it so far as Davenport, where some kind soul opened his home and offered a couch and free spinal adjustment. Woot!

Greg is becoming more responsive. Crossing & uncrossing his legs, etc. They're turning down the respirator tonight to see how he does breathing on his own and will take out the tube if all goes well. Then he will likely be moved out of ICU tomorrow. Everything sounds encouraging so far. Thanks for the prayers and kind thoughts!

Will drive the remaining six hours and go straight to the hospital tomorrow.
