Actually, CB, I'm originally from Chicago, and first heard of Milorganite while living in Miami.
When my husband worked at the Urban House, they used to give tours that included the compost heap. The tour guide would shove his hand into the middle to feel the heat of the composting process, and all the tough and sophisticated folks on the tour would do the same, with an understated casual air. Then the guide would mention that the compost included graywater from the "urine-only" toilet (the Urban House had three toilets, all different), and the ones who had shoved their hands in would all start surreptiously rubbing their hands on their pants. Most entertaining.
