groping for consensus sounds too much like fame fagging.
there can be no known consensus here.
you are on the North coast of San Francisco. You need to be on the other side of the bridge to be on the West one.
The so Called 'East Coast' really faces in all different direction. So does the 'West Coast.
divison about which coast is just kind of lame.
PS: the West Coast of New England is called
Lake Champlain, Vermont. It's nicer than anywhere in California. Don't tell the Westies!
