Hi Motobazzi , like you we've been to Tassie three time now on the bike, the trip last week saw us do close on 3500k's on the Isle , the bulk of which weren't on roads we've done before.
In terms of rain , its a given every time the wife & I go away it rains.. Hence my mates call me "the storm chaser", or "drought buster".. next planned weekend away is ANZAC weekend on the MGCoV ( Moto Guzzi Club of Victoria) ride to Corryong . If your planning to come along , bring your wet weather gear
