The Tower is hiding

I often blip Alloa Tower but today it was hiding in the mist at the end of the Avenue. A bitterly cold morning that required me scraping the car. The mist and fog hung about till lunchtime. 
Lots of meetings out and about today and then a nip to the hairdresser rearranged from the other wet weather weekend. 
The radiator issue is baffling me. One has suddenly decided to work but another one has stopped....Engineer can look at it all soon.
