Although I have never personally met Gunboat. I have seen his name and activities here on the forum.
If it is going to be more about his personality and less about motorcycles then I suggest one or more of the following.
service to country
service to community
service to a fellow person in need, regardless of situation
an outstanding or unselfish act that had benefit to others but no benefit to the provider
service to their respective church (this may be touchy for some people of other or no affiliation)
unique and unselfish act ( no specific offered, and must be submitted by anyone else other than the provider)
There is my 2 cents worth.
