Meeting point / time - Murchisons Gap 0830.
7 Cars joined the trip (Colin, Julia, Glen, Chris, Zoran, Anthony & Jamie). We did the route as planned except the first turn on Davis Trk which is gated.
Unfortunately Chris broke a CV joint mid morning and to save further damage, left at that point. We had lunch up the top of Tehans 2, with the majority of the planned tracks completed, showing good progress. In the afternoon we went looking for some new fun, found a few tracks we could not do (RoofTop maps "steep" part of Jenkin Track -over the bridge, Jenkin 1 and Rocky Track). but we enjoyed Tehans 4,5,6.
The other gotcha was we could not find the bottom of Tehans 3, which according to the Hema and Rooftop says it starts in the campsite. So we will need to start from the top down next time - any excuse to go again 
Thanks to all for making my first leader trip a positive experience, thanks to "Greg (94_200TDi)" for some local advice, whom we saw at the meet up and out on the tracks. Finally thanks to my navigator Daniel, who was always one step ahead.
I will add some pictures/videos to the Facebook page.
This is the list of the tracks we successfully followed, which could be used for a future trip. Note I originally called this Medium becuase a few weeks ago there was more water about and it was more slippery. However in the drier weather this would be a Easy-Medium for the right set up vehicles.
