These are awesome images Paul!, I'm glad you got the chance to go out and document this frozen river on camera, I heard about the event from the BBC NI website and saw one image but I have been eagerly waiting for more. The images are excellent, I love the crazy structure to the ice under the bridge and the tree branches leading the eye into the first image. The portrait image is a beauty. It really is difficult to believe the Sprule has froze over for the second Winter in a row. There could be more to come!. Thanks for sharing.
* Never sick of seeing snow and ice images
