Our riverside walk with the railway bridge that carries the main line Norwich to Liverpool Street trains.   
It was -4c this morning but despite this the frost has thawed from the trees and areas where the sun gets too.    Interesting that the frost hasn't destroyed the duck weed on the river and that its iced over in places.4
My patio is still like an ice rink and also some of the footpaths still have sheet ice making it tricky for walking.    Luna raced from the garden onto the patio this morning and slid from one end to the other before banging into the patio door.   Since then she's using a different route down to the garden !!
