<p>&#39;Dune is a four-letter word&#39;, said Griselda Sprigg on the first day of her family&#39;s attempt to make the first motorised crossing of the forbidding Simpson desert. &#39;And&nbsp;so is bloody spinifex.&#39;<br />

<em>Dune is a Four-letter Word</em>&nbsp;tells the story of Griselda and Reg Sprigg&#39;s pioneering desert adventures - not only in the Simpson Desert but all over the vast Australian outback. Griselda&#39;s story is also the story of Arkaroola Sanctuary, how she, with her husband, Reg, turned a drought-stricken sheep station into the magnificent flora and fauna reserve and tourist mecca it is today.</p>
