Yeah, Madison, Indiana, is probably the only place in the country where the unlimited hydros are more deeply ingrained than in Seattle. It's a heavily northwestern thing; look at the 2014 schedule, which is a lot like the schedules they used to run when I was a kid, except I'm pretty sure there wasn't a race in Qatar in those days!
Out of seven races, two are in Washington State and one in Idaho.
Kind of like the Green Bay Packers; socialized supersports.
