compound adverbial diagram

[Kondorosi]

Keeping your lips zipped when things sour is the best piece of blunt marriage advice the couple will offer in their sold-out appearances at the Louisville Public Library tonight and on public radio station WFPL tomorrow morning.

Try this. I am especially interested in the bolded parts.

I still have not yet figured out how to diagram with a keyboard, but maybe I can describe what I would do about the boldfaced words. The two prepositional phrases I would make compound and then take short horizontal lines to the left from the prepositions and from those short lines run sloping lines down. On the sloping lines I would put "tonight" and "morning". From "morning I would similarly take a short horizontal line to the left and from it a sloping line down. On that last sloping line I would write "tomorrow".
I guess you could say that there is an understood preposition before "tomorrow morning" and do it a little differently.
I would demonstrate the modifications from the prepositions as a way of showing that the whole prepositional phrases are being modified.
Maybe I will see if H&H has anything like this.
Interesting.

Actually, driving home from school, I was thinking about how to show modification of an entire prepositional phrase. Maybe that's why in H&H they diagram prepositional phrases with little extensions at the bottom of the preposition line -- extensions that go slightly past the line that goes off horizontally to the right, on which the object of the preposition rests. That little extension could serve as a "handle" to attach to the whole phrase.
I have never understood that before.

It is not the syntax of the sentence but the mind mapping of the diagram that gave me the most headache.

[Frank Antonson]

That's a pretty tricky sentence -- and a fun one.
Those adverbial prepositional phrases are not drawn quite the way I would have drawn them, but they are close.
I agree with all the rest of it -- and that part too, in principal.
Today I will try again to figure out how to diagram online. I should also trying scanning a diagram and sending it to you as an attachment to an email.
Would you privately send me an email address that I could use?

I have managed to do a (sort of) diagram.
Now, how do I import it to this reply?
