Need the city to allow it to happen. ISU as I remember wanted as such, but as the CU game taught us we need to differentiate between a Cyclone siren and a tornado siren. I still think we should do it.
I guess people cannot look out thier window to see what the weather is like, or turn their TV or Radio on when they hear the siren 7 Saturdays a year. Its not like its 1940 when not many had TV. Heck now we have live megga 10000000 watts super 3D doplar HD that can zoom in so close you can count the blades of grass on turf at JTS. Dont forget there is a sky cam on every grain leg in Iowa as well.
