We have been having a very unusual winter with several spells of above 0 temperatures which leaves lots of water sitting on the sidewalk at the corners of the house. Slippery-when-frozen kind if water.
Somehere in our travels we saw chain used as a sort of downspout so we thought we'd try it.
And we are maintaining our reputation as 'the steange neighbours'. Our friends next door had to come out and see just what we were up to now.
