So San Francisco/San Jose/Oakland and Seattle/Tacoma is on the at risk list because: "relatively high numbers of residents who watch analog over-the-air television broadcasts and relatively low participation in the NTIA's TV Converter Box Coupon Program."
but how many of them don't need the converter box coupon? The Bay Area is home to Silicon Valley, would it be safe to say that a large number of them have purchased HDTVs and don't require a converter box?
