I would recommend you carry every bit of wet weather gear you can, WHY.......... when I road across Tassie for 5 weeks I loaded enough rain gear to cover the entire state, and I swore up every hill I needed
to get rid of some weight, on that entire trip it only rained once on the last day, not only was my rain gear a total waste of time and energy it was my omen to perfect weather.
But sh** like this happens to me....my last trip I was warned about how little water was about, so I made sure a carried a heap................................there was so much fresh water on that trip
I was swimming in it in the afternoons, but hey, at the end of the trip my calf muscles were big enough to eclipse the sun :-)
