The important thing you should know is it was a hit-and-run. "WE NEED YOUR HELP!!!! Sunday around 5 p.m. Gilby was riding his bike in Sherman Oaks, California. He was riding south on Woodman and at the intersection of Moorpark some idiot turned left right in front of him. Gilby hit the passenger side of the vehicle. The driver took off. "Here is what we know so far. [Pickup] truck light color tan perhaps silver. There was a male driver and possibly a female passenger could be Hispanic, but not sure. The truck looked fairly new and has damage on the passenger side. "If you have ANY information, send me a direct message on Twitter until I find out the police department. "C'mon, someone knows something. Look for that truck. "Gilby is currently getting ready for surgery to his leg. It's a pretty gnarly break."
