Did you camp on the mountain at Bathurst, it was brilliant fun back then. Hope someone knows the bloke. Be a great ending for sure. My gravel rash story came after I crashed years ago on the outskirts of Narrabri. The local GP, charming arsehole gave my 18-year-old self a lecture while I was dripping blood on his surgery floor about being sick of fixing Motorcyclists and he wasn't interested and I should piss off to the hospital, that I had no idea was there. The local Theatre Nurse dressed the gravel rash, it was on my shoulder and BAD. So I continued to Serate in Queensland where I discovered I also had it under my armpit. That scab had formed through my T-shirt. I spent the next week turning up to that One Nurse Hospital in Serate having the dressing changed. Those dressing kept sticking so every day the scabs came off again. Those Nurses were fantastic, horrible job but they did their best for me. My first and last bit of Gravel rash, I learned a good lesson about wearing gear in plus 40c. BTW Mad Max 2 was filmed as Silvertown as well. I have a story about that as well. Not now though.
