To celebrate the nation’s 250th anniversary, I’m kicking off The 50 States Project, where, approximately weekly, I’ll talk about something state-specific.

If you have quirky state-specific stories, send them to me, and they might turn into a blog post. More about this little (actually big) project another time…

And is there a case for WA State excise tax to reduce federal income tax in another way?
