View all 16 ReflectionsRobbie (Robert) Mahn was a classmate from first to 6th grade then from 7th grade through high school in Athens, Ohio. His house was next to my best friend Bob Nelson.
Robbie was just a great classmate I was truly devastated to learn of his accident.
My wife and I are going through Yellowstone in August so I thought I would take a look to see if there is a memorial to Robbie somewhere in the park and came across this site.
I apologize to Grace for this late posting. Robbie Mann was one of my best high school buddies so I will miss not seeing him ever again. I hope you are doing well. God Bless. Be safe.
