It is truly beautiful out there mate. I intend to do a 4WD trip, 3 to 4 months time.
Only a few days, after the rains this year, the wildflower show will be spectacular.
After a rain the deserts turn from red dust to the most vibrant and riotously colourfull place I've ever seen.
And personally, I don't see how an "interplanetary superhighway" can do any more damage than we already have.
Hell, the British blew half the southern end of the deserts away with A bomb tests during the 1950's. And the Monte Bello Islands off the North West Cape copped that treatment as well. What the hell else can we damage after that.
Aren't we just using a glorified railway line, and a couple of million superconductor magnetic impulse driver units? Solar powered of course, because we are environmentally aware, crazy people. Oops, I mean scientists.
