We get fog, and no this is not a new discovery. But when we have it, it is usually a pea souper. The other thing about our fog is that they usually do not lift until 12-1pm.
The reason for this is that our place is not at the bottom of the valley. The main street and township of Yass is at the bottom, but we are approx 2km from the GPO and up the ‘hill’. So as I type this at 10.39 am the fog is infact getting thicker as it raises from the town. So sometime around lunch (or soon after) we will see the sky.
