Why not go right to the source? Bob Riggle is alive and well living in Arizona. Look him up I'm sure he'd be willing to chat. I met him in my local area about 10 years ago and we had a very nice talk for almost 2 hours. What a neat experience that was. My last name is Reagle ,My dad's name was Bob ,I grew up in a 65 Barracuda and ALWAYS knew what the original Hemi Under Glass was. When I was a little kid I remember hearing them announce "Bob Riggle and the Hemi Under Glass coming to ***** Drag Strip". Sounded to me like they were talking about my Dad!!! I told my story to Bob and then asked if he was looking for a protégé since he would probably have to retire someday. He grinned and asked "Would you consider changing the spelling of your last name?" It was a day I'll remember as long as I live.
