The Diagonal in the Greenup Series of House Greenup

Baker searches for answers within Floydada, perhaps in vain or at least Washington, D.C.

10:51pm update:

I now think that the position of the 3 yellow submarines in Greenup 16 (and the parallel 3 burning cars of Greenup 15) might be related to the several successive master number locations on Tiretta’s Bank of Despair, as Hucka Doobie has dubbed it, perhaps specifically to Baker’s 3 expanded master number series there of 35, 36, and 37 all. See here for an illustration.
