Other interesting editions (IMO), in no particular order:
Montana: a hodgepodge of black bullets, white bullets, and split bullets (black/white), with no rhyme or reason as to markets. It had three channel 4s, three channel 6s, and three channel 8s, again, without regard to markets. By the time you get to the point of listing three channels with the same channel number, you really need a separate edition.
South Georgia: an ambitious little edition that tried to cover everything from Atlanta to Tallahassee to Jacksonville (4/12 only) and Savannah. It was the default edition for Tallahassee. Interestingly, its coverage area extended all the way from the Gulf of Mexico to the Atlantic coast of Georgia.
Northern Colorado: kind of a misnomer, its coverage area was actually large portions of South Dakota , Nebraska, and Wyoming, as well as a tier of counties in extreme northern Colorado. Back in the 1970s, I got a TVG circulation map (long since lost) that showed much of this area as simply not having a TVG edition. IIRC (I could be totally wrong on this) any subscribers there got the New York Metropolitan edition. That whole area historically had widespread viewership of Denver stations; it would have made more sense simply to send them the Denver edition and let them figure out which local stations corresponded to Denver network schedules.
Carolina-Tennessee: the default edition for the Knoxville, Tri-Cities, and Greenville-Spartanburg-Asheville markets. Its coverage area stretched all the way from southeastern Kentucky to Newberry County SC, and it contained Charlotte listings as well. Newberry County, despite being in the Columbia market (from the mid-1980s on), stayed in the GSA edition (one of the successors to the C-T edition) coverage area all the way to the end of regional TVGs in 2005. Viewers there get stations from both markets OTA, not sure whether Newberry cable carries GSA anymore.
IIRC, by the 1990s Tallahassee was using the Gulf Coast edition of TV Guide.
