When was the last time WWE held a big PPV in a city of less than 500,000?

I'm talking the big ones. Royal Rumble, WrestleMania, Summer Slam, Survivor Series.

Watching the 96 Royal Rumble which was live from FRESNO! As of today, after over a decade of steady growth, Fresno, CA has broken the 500k mark when it comes to their population. Considering markets like Chicago, LA, New York City, San Diego, Miami, Philadelphia, and other major cities can make a lot more cash in markets where their base city has a population of over a million, Fresno no longer seems like a good choice for a Pay Per View.

So it's a simple question- when was the last time WWE held a major PPV in a city with a population of less than 500,000?
