D Whysong and I have been carrying out a mid-IR survey of 3C radio galaxies to see which have IR-excesses, interpretable as hidden Type-1 AGN. Mostly due to relentless bad weather, we have a modest collections of observations so far. However, we can say with confidence that some radio galaxies are true kinetic, nonthermal emitters, with negligible energetic contributifrom a visible or hidden Big Blue Bump. To make up for the modest collection of mid-IR observations so far, we also present a new spectropolarimetric discovery regarding the underlying shape of the quasar Big Blue Bump in the Balmer Edge region, a fairly radical view of quasar reddening, and a bit of Keck adaptive optics data on Cygnus A and the ultraluminous infrared galaxy NG...
