IN its basic sense, the name "BOG" came from "Beveridge -on-Ground", and indeed one of adequate length should behave similarly.
I don't know either of the two people you mentioned, but any of my interactions with 160 meter guys have resulted in some very strange ideas....

There's been a fair bit of hand-waving on the topband list about the BOG over the years, partly because anecdotally, either they "don't work", or that they have very good F/B. K2AV has done a lot of measurements, and seems to conclude that a proper BOG (not a wire near dry ground) is actually a resonant antenna, http://www.iv3prk.it/bog-modeling.htm puts forth the same idea. This is for the limited frequency range of 160m; the entire MW band might prove interesting depending on length, ground conductivity etc. I'd assume that a BOG at Grayland especially in the summer would act more like a Beverage. Did you ever compare a "BOG" with a raised wire there?
