There is an odd combination of care and mockery with regard to infrastructure devoted entirely to sinkholes. Please, please go to thesinkhole.org and check them out. It is not a complex blog, but it is dead serious (for example, note that a number of the stories covered by the blog record casualties). A curious resource and one to keep your eye on.
