A friend of mine actually climbed an Indonesian volcano where this took place (I'm not sure whether there's more than one) and met some of the miners. Just think how that would look at a job placement interview. "So, what other skills and experience do you have?" "Well, I can climb an active volcano and bring back sulfur from its crater..."

It's also worth stopping to think what happens to that sulfur afterwards, won from the mouth of a volcano. It could well be in the food you eat, or the tires of the car you drive...
