I'd read that stringing a length of copper wire over the ridge kills
moss,

have been falling down almost every day. Maybe the copper wire takes
time to
work?



Has the copper wire gone green?



I recall an old church somewhere with a glorious green copper roof on
its spire. We stopped and admired it. Another tourist commented that
they should polish it.
