Like I said there is one on a highway from renton to issaquah. I've driven it at work, and ive been wanting to take my teg down it, a couple few good corners
and then from issaquah the same highway can continue out into redmond, but its nothin too special out there, just goes along lake sammamish...and that's a long drive for you.
Lol there's always 509, the "burien international speedway". Never, ever any cops out there, but its a freeway.
Other than that, all the good drives are way up my way...A LOT out in Arlington, those are my stompin grounds
