Summarize civil engineering professor Vito Vanoni's conversation with the author.

The author talks with civil engineering professor Vito Vanoni, who claims that residents are not protected by debris basins. When asked where he lives, Vito replies that he lives below Eaton Basin. The author finds it ironic that the professor lives in denial of his own expertise. Vito says he feels safe because he's seen no mountain debris in his yard since 1949.
