For a number of years now there has been a Common Ringtail Possum's nest in the farmhouse garage. The possums chose to build a nest in the rafters where a roll of pipe has been stored. Successive generations must use the same nest because according to one reference I have they only live three or four years. We check that they are present occasionally but try not to be too intrusive. We often see one out and about around the garden after dark.
I'm afraid the pipe is 'out of action' for a while yet.
