Bucket on a chain

Not a very good day for blandering today - my lunch time blip-wander was cut short due to a brief rain shower. Only managed a quick jaunt round Thistle street and back along George Street before heading back to the office. Spotted this fag-bucket with a mysterious chain descending in to it and decided that I had my blip.
Looking forward to tomorrow - half day off work to go for our 20-week scan!
