Modesto and Stockton are outside markets and usually are talked about in the Central California Board. Merced is also very close to Fresno. The media in Fresno usually refers to the region there as Central California. In Sacramento, the region is usually Northern California.
Just because the people set up the board with Central California as (everything market Bakersfield which is Market 78), Most all of the talk on that board is: Fresno, Bakersfield, Stockton, Modesto, Merced and the Monterey Bay.
The Sacramento board is used mostly by people discussing stations in the Sacramento Region.
I can see where you got that by the header in the market, but that's not how they been historically used. Also, since you were talk about KDJK's signal south of Merced, you were even further away.
