NCAA regional sites for 2020 and 2021 announced
by Mr Wednesday (2019-04-20 00:56:03)

2020: Worcester, Albany, Allentown, and Loveland CO (looks like it's about 30 to 40 mi north of Denver)
2021: Manchester, Bridgeport, Fargo, and Loveland again

I'm guessing they had some trouble getting bids for 2021, otherwise I doubt they would have repeated in Loveland.
