Nice one! Been to Kawah Ijen in September and still can't get the sulfer smell fully out of my backback ;-)

My eyes and lungs were burning when getting closer to the pipes and I can't image doing that all day long as a job.

Gone be posting some pics too in part 2 of my 4 day - 3 vulcano's blog :-)
