That one wasn't that acrimonious, and it it did get people lining up on different sides for non-political reasons and in different formations than usual.

I suspect from what I've read about it that I would find the Campi Flegrei rather disappointing, having been round Whakarewarewa, Hells Gate and nearby places in the Taupo volcanic field long before it got to its present level of touristiness. (My father knew the chief vulcanologist for the Rotorua area: he kept his car permanently fuelled up to the max, boot full of shovels, planks and ropes, with the garage door always open and everybody in the family having a spare set of keys).
