First off, I'd like to thank each and every one of you for all of your prayers for Dave and his family. I know that they are making a difference. Please continue to pray for him.
We have more details on what happened. Evidently he was riding and a Jeep made a left hand turn in front of him. He slammed really hard into the side. The passenger of the Jeep was also taken away by ambulance at the scene. From what we've been told, Dave has "massive" head trauma, C1 and C2 fracture, broken left knee, broken left hand and internal bleeding. He is still unconscious but not in a coma. He is stable enough to have surgery to repair his knee and hand today, which is definitely a good sign, though he is still in ICU.
Please continue to keep Dave in your prayers, he still needs them as he continues to recover. Things are looking up, but he's not out of the woods yet. Please also keep the passengers of the Jeep in your prayers. I have no other details about those individuals at this time.
Thank you again for all of the prayers. I'll update again as soon as more information becomes available.
