Me neither, but James G. Cummings of Belfast, Maine, had (quoting Wikileaks) "four lots of one gallon containers of bomb-grade hydrogen peroxide, uranium, thorium (also radioactive), lithium metal, thermite, aluminum powder, beryllium (radiation booster), boron, black iron oxide and magnesium ribbon" which he somehow planned to set off at the inauguration. Personally, I don't think that volume of material could have been easily smuggled in anywhere near the inauguration activities without raising suspicion.
Why no press coverage of this story, apart from the Bangor Daily News?
Wikileaks has a summary; Wonkette has summarized that; the Washington D.C. Regional Threat and Analysis Center report (PDF) is here.
