Over the years I've grown and toked (since the early '80's) and all the back and forth hype I've heard that overall the Pac NW, Portland to Seattle, has the best relative to availability range. Cali has the long history of Humbolt and Mendicino Counties behind them and there's a lot of really good smoke available there by volume. Living in Seattle for years may seem to make me biased. But time and again I've heard and read in High Times and elsewhere from folks who travel alot that the Pacific NW region has been known for supplying some of the best bud in the world since the '80's. In 1999 I knew a grower who worked an unknown strain pheno that was to date the best mind blowing S#!T I've ever smoked before or since. It was so overwhelming in terms of potency and quality of soaring blast-off, kick butt high you'd have to experience it to believe it.
