I may be older than you are, but you probably know more than I do. Tulsa is just a name to me, either one of which I've never heard or simply about which I've never learned anything. One thing I can do, as the last sentence shows, is write sentences that don't end with prepositions. But, if you ask me, doing that can make them sound worse sometimes. I think the "of which" and "about which" are annoying. This is even worse:
"A preposition at the end of a sentence is something up with which I shall not put."
– Some scholarly guy who didn't like prepositions at the end of sentences; I don't remember his name.
Oftentimes, I intentionally end a sentence with a preposition because I think it sounds better that way.
How's that for changing the subject?
