Just saw a hazelnut ice cream at the store. It’s Blue Bunny brand, called either Hudson River Rapids (I think it was Hudson, might have been another river). I can’t find it on the internet- something screwy is going on with Google.
It’s not Wavy Gravy, but it might help.
Heh. Did you know he had a book out? From years ago now. It’s kind of autobiographical, about his work and the kids camp he runs, etc. Seems like a nice guy, very down to earth.
