I was listening to a re-broadcast of an interview with the 2010 Australian of the year, Patrick McGorry, on ABC RN
http://www.abc.net.au/radionational/programs/conversations/patrick-mcgorry/6834896. He briefly mentioned that he had done an overland in the late 1970s, and was in Afghanistan during a revolution in Afghanistan.
I guess that was the Saur revolution of 1978 which, as I have mentioned here before, Brendon Reid and I were caught up in as well (along with the late Travers Cox). We ere on an eastbound, but he was on a westbound.
I recall that there was an Encounter Overland truck there as well; we visited it after curfew, which we got away with. They were listening to the BBC World Service, which was reporting the events, but were talking complete BS.
Patrick mentioned the super-thorough customs searches going into and out of Iran at the time.
Does anyone know who else was in Afghanistan then? I don't think there were any other Capricorn or Sundowners coaches, but he did say he was on a bus.
