Christopher Reeve's Son Retraces His Dad's Last Adventure

To ABC News reporter Will Reeve, "Superman" actor Christopher Reeve was just simply dad to him. Will was two when his father was paralyzed in a horseback riding accident, and the "Superman" actor died when Will was just 12 years old. The special "Finding My Father," follows Will Reeve on a journey from Mexico to Alaska. It's the same trek his dad took 30 years ago. That was his last adventure before the accident.
