Sesquicentennial

I love the word sesquicentennial. It’s a shame that it doesn’t get used much.
Thank goodness for my state’s urban blight and rural renewal program.
Every week since its establishment two centuries ago, a new village or town was established.
Which means there’s plenty of sesquicentennial celebrations to be had.
Bicentennial celebrations, however, are a rarity, since all population centers are razed and resettled after 150 years.
It’s meant to ensure legacy sewer, power, and road infrastructure are replaced with technologically efficient innovations in the new locations, but I think people just like to watch stuff implode, crumble and burn.
