Blewett is really different depending on whether you're approaching from the north or from the south. From the north is much steeper and shorter. When I lived near there, I would go up from the Leavenworth/Cashmere side, crest and go back. The downhill on the north side is great. In what might not be my brightest decision ever, I passed a car going down.

There's some other nice climbs around the Puget Sound area too: Crystal Mountain Blvd, NF Road 25 south of Randle, Longmire-Paradise, Skate Creek Road. The list goes on and on.
