I went to a computer group meeting recently where the speaker was a person who had ridden his bicycle 17,000 kms around Australia - and had kept in touch with his students over the internet as well as used a range of other rather sophisticated (to my mind) computer applications from very remote locations. However, it seems a publicly-accessible blog wasn't high on his list!
Amongst other interesting tidbits of information I picked up - apart from the strong resolution never to do anything remotely like this myself - was that, if you do decide to ride around Australia, you do it anti-clockwise. It's well known that this is because you'll have the wind behind you as you cross the Nullarbor. But the speaker had an additional reason: because you're on the left hand side of the road, he reckoned it's 16 km shorter in that direction!
On a somewhat related note, another former colleague and her husband, with their three children, are currently getting to the end of an extensive outback tour, although in their case they're using a Prado and camper trailer. They have maintained an impressive and regular blog.
