I have spent a LOT of time in the last few days, looking at high shots of the Alamo Dome. I see what appears to be four towers above it.
Lightning rods? Cellular Towers, all foxed up? Minarets to call the loyal? Does anyone know what these 4 tower like shapes are? They looked pretty in the late day light, and in the floodlights used at night.

Well someone is going to do it, might as well be me. It’s Alamodome. There is no space. 
Why, may I ask?
My family lives in San Antonio. While I’ve driven by that thing many times while fleeing north to Austin, I have been to the Alamodome only once, for a Spurs game (they lost). Anyway, I’m pretty sure they’re just there for decoration. The towers, that is, not the Spurs!
They hold up the dome. Think of a suspension bridge, and the two support towers. This is the same idea in three real dimensions. The cables coming down from the towers hold up the high points of the roof, countered by cables on the opposite sides of the towers (90 deg apart, but the resultant vector is opposite).

My Yankee snowbound brain was about to cry out in protest, but I realize that any public arena built in southern Texas does NOT need to be built to withstand millions of tons of snow and ice gathering on its roof. 
It’s pretty enough, a different kind of arena than I’d seen before.
rinda rinda, I had been making television that included a LOT of so-called “bumper shots”- those wide shots of an arena you always see going away from a program to commercial, or returning from commercial to your hosts. We had hosts in a white tent across the street from the AlamoDome ( Sunset Station? Is that right? ). They were inside their silver Airstream, when it rained and out under their white tent when it was nice. Anyway, I got an eyeful of the Dome- and from above, too. Saw the spires, saw the roof, didn’t understand.
Lucky for us, we have Uncle Bill.
