Not happy - the tire exploded again 20k later. I put on my spare tire and used yet another tube - they were declining a little too quickly now. I know people just wanted to be friendly but honking at me standing in the hot sun with massive roadtrains passing and hundred flies trying to penetrate every hole in my body (I couldn't use the headnet) seriously annoyed me. If you mean it - stop and ask if I'm okay or just to chat a couple of minutes. Aussies' prefer the noncommittal wave or honk - don't get involved...
