I awoke this morning to chilly overcast skies and then during my morning coffee it started to rain! Just a drizzle that the desert hungrily ate up as the drops hit the dry floor. I wasn&rsquo;t expecting rain in the Simpson that&rsquo;s for sure, but more worryingly if it carried on and got heavy it can cause flooding resulting in the tracks being cut-off. Occasionally during the year flooding swells the dry salt lakes and river beds and they become completely unpassable and this can happen any time up until July. The thought occurred to turn back then, I was about 170km in from Birdsville but the rain was very light so I kept an eye on the clouds and decided to carry on.
