A whole lot of things go way beyond my ability to understand.

I don’t get Donald Trump’s continuing presence at the top of polls gauging the Republican presidential primary; I don’t understand how scientists are able to calculate when Earth is closest to Mars.

Nor do I understand why Amarillo City Hall and Downtown Amarillo Inc. have said “goodbye” to each other.

DAI executive director Melissa Dailey quit her job on Monday. On Tuesday, the Amarillo City Council ended its financial relationship with the non-profit organization. There will continue to be some kind of relationship, although it’s still to be determined.

I have to ask: How come? Why end a partnership that so far has produced significant movement in the revival of the city’s downtown business district, with more projects yet to come?

Council members spoke well of Dailey and all that occurred on her watch at DAI.

So, then the council decides to end its financial ties to the agency. Interim City Manager Terry Childers spoke of a “new phase” of downtown redevelopment.

I look around the central business district and I see plenty of work that’s already been done. New business has sprouted up. The Fisk Building has been turned into a first-class business hotel.

We’ve got those three huge projects — Embassy Suites, a parking garage, and the SPS office complex — under construction.

I drove to Fritch this morning and sped past the new Coca-Cola distribution center at the business park where relocated from downtown. The old site? It’s going to make way for a downtown ballpark.

All this happened on DAI’s watch . . . on Melissa Dailey’s watch.

She’s gone. DAI’s future now is limbo. City Councilman Randy Burkett referred to it possibly going away in the near future.

Why is the City Hall brass monkeying around with a successful formula for creating a resurgent downtown?
