Simpson trip vs Birdsville races

Yeah mate traffic travelling to Birdsville from all directions increases quite a lot, and quite a few use the races as an excuse to do a crossing (before and / or after). . . but really, if you're doing WAA / Rig or parts thereof and avoiding the more direct French Line, you should be ok.
I will never do it again in peak months, this July was so crowded, delays at dunes quite regular, and radio calls were almost a waste of time (just too many, and half didn't know where they were anyway !).
I wouldn't worry about it too much, but if you really want to do FL all the way then just be prepared for slightly longer days.
There are no problems finding places to camp, just some dune corridors might have more than one or two 4Bs using them, especially the nicer ones.

We came through west to east one year and ended up in Birdsville on race day. Quite a few ute loads of territory locals use the simmo as a short cut to the party. You'll be meeting a few of these guys on their way home. We found them generally well behaved and good company.

Thanks guys, this is what I was expecting, had a look at the itinerary I've been sent, and arrive in Birdsville on the Tuesday after the races.. But we are going to spent a couple of nights in the one spot.. Just to soak it in.. So we won't be in any hurry.. But you have confirmed my thoughts, we will be a lot more cautious when cresting dunes.. Cheers fellas.. Odog
