Rough estimate from http://en.wikipedia.org/wiki/List_of_U.S._states_and_territo... suggests that about 2/3 of americans live in a state bordering the ocean, so about 100 million americans further away from the shore.

What that has to do with anything, god only knows, unless you meant something like '100 miles away from the border', and even then I'm at a loss.

Go visit a flyover state sometime. Most of the country's very different than SV/the northeast corridor/other modern urbanized area, and I wouldn't live there if you paid me.
