I personally don't think the world is going to end based on street sign grammar. That being said I personally do not think punctuation has a place on street signs.
I love to collect street and business signs that have crazy grammar or illogical sayings. They can be so funny.
I especially like the sign that says "Slow Children" Don't parents mind that their children's diminished capacity is being announced to the whole world? Wouldn't you object if someone placed that sign in front of YOUR house where YOUR children waited for their schoolbus? hehehe
I agree JennsPeeps. But, I enjoyed English class both literature and composition. We had a teacher in 7th grade that made us memorize practically all of Strunk and White. You will know that one. We even had to diagram sentences which I am sure no one does anymore. Sure made one aware of participles that dangled and verb tenses that didn't agree. As you can tell I graduated before the mid 60s.
My daughter graduated in 2006. She had to diagram sentences and dangling participles drive her crazy. She learned it in school, but my wonderful wife really drilled it in. My daughter is now one of the editors of her college newspaper in Boulder. She is getting a bachelors in journalism. They still teach that stuff.
I was one of the ones that fell asleep in those classes I've always done good instead of well.
Several of the smartest people I know do well to spell their name right or write a paragraph that isn't full of grammar/punctuation that'd have a hard time getting past an English teacher or someone who likes to put others in boxes labeled "Doesn't Speak Standard English". That's okay though, they're very rich and pay a lot of taxes that keep the language teachers employed.
