Speaking of KCK, while watching KMBC9 They were going over the damage up by i70. Towards the end of the movie clip here, you can see a 2001 - VERY close by the damage. On the higher quality video of this link below I think this siren got a good whacking when the tornado rolled by.

I will try and extract the HD image of it from my DVR to the computer later today, if I don't become side tracked by the storms first!
