Finding Northern California

What makes Northern California an identity, beyond simple geography? What are the common ideas that forge such a diverse area together? What are the unique local traditions and events that are part of the tapestry of the region?
Northern California is large region, by itself larger than many states. Three of the boundaries of the area are easily discernible: The Pacific Ocean in the west, and the state lines in the north and east. But south, the end of Northern California is less clear. For a lot of people, it is a general line that connects the San Francisco Bay Area to Sacramento and on to Lake Tahoe. This may be simply the general area of influence these significant centers (San Francisco, Oakland, Sacramento, etc.) have on the less urban areas. However, there are certainly other people I have known from south of that arbitrary line who would argue. Certainly, the argument can be made that the southern line of Northern California aligns with the the southern borders of Monterey, Kings, Tulare and Inyo counties.
These are just lines on a map, however, I would like to take a few weeks and go find out how people view Northern California and how they define it, either as residents or visitors. I want to visit the community events, talk to the people and learn some of the history that makes Northern California an identity. Along with the interviews and narrative, I will include contemporary and historic photographs of this diverse region, from the coast to the Sierras.
Ultimately, the project is about the search for the meaning of community. Practically, it will allow visitors from out of the area to better understand the differences in regional identity in California (I'm looking at you, Germany, Russia and Greece). It will also be for the residents who live here and may see a different aspect of this fascinating place we call home.
"Finding Northern California" will result in a series of articles and a book for travelers and residents alike. I hope you will help. Use this link to donate or send me your thoughts on what it means to be from Northern California. Let me know where I should go and who I should talk to.
Writing is often a collaborative effort between two or more people. Collaborate with me in "Finding Northern California." Make a donation to my GoFundMe campaign through the button on the right or drop me a line here with suggestions or comments about Northern California.
