I was just talking to a guy (in his 50's) last night over dinner about that very thing. How it would be cool to make an adult size Big Wheel and cruise around parks in a big group. Now I gotta make one for me....eeerrr... my son.
If people think it is stupid, I can just start drooling all over myself and they then feel sorry for me. If we all get together to do this, we'll all have to show up in a short bus. Our ticket out of ridicule!
