March 22 update
So what does everyone plan to do this spring? I've signed up for the Cantrell/HOD days on April 20 and 21.
I've also committed to three sets of two days with Porsche Train at ORP. Not sure of what sets of dates to attend yet though.

Added Oregon PCA advanced lapping days. All their advanced days are
preceded with a conventional HPDE day.

Added and adjusted some more Proformance days

Clarified Vancouver group at Ridge as Bullet – format TBD

Added some more Turn2 days

Following is a listing of 2012 track days throughout the Pacific Northwest
and Northern California and a couple of other side-trips. I'll update/edit
this list as other days become available. If you have any to add, just let
me know. I'll update the list somewhat regularly.

Some excellent multi-day, multi-track combos here!

This is simply an informal listing of events I've found. Consider it a
starting point for planning purposes. Dates can change, or be added or
deleted. Ensure that you check the appropriate sites if you have a
particular day in mind. Many other clubs and groups will hold events in
addition to those on the listing below. If you come across something you
think others would be keen about, please let me know or post it here. I've
tried to focus on groups that I know and with which I have experience.
Most,but not all, are run in more of an open format vs. a more traditional
DE day. There are many more traditional DE days available. Please note that
some of these days such as Porsche Train are by invitation only. If you know
a fellow driver attending such an event, he/she may be able to introduce you
to the organizers.

Others to follow soon. Others suggested?

Notes:

I've included Proformance afternoon lapping days if they precede full sport
lapping days. If you only want to do an afternoon, they have many more
choices. See their website.

Ridge first-timer day and refresher days are available throughout the
season, some before hi perf days. See their website.

Dean Conti has run the Ridge many times already. He is coaching for the
Ridge Group track days, and possibly others groups. You might remember the
tail lights of his silver Z06, (that he has raced around the country),
disappearing in front of you at Seattle or ORP. He has coached with
Proformance as well. If you don't know him already, and would like to hire
him, contact me and I'll connect you.

I've made Laguna Seca my southernmost track. Buttonwillow, Willow springs
and others further south also have days worth considering – long drive
though!

Non-driving events to consider:

Aug 11-12 – Pre-reunion at Laguna Seca
Aug 14 – Carmel Concurs de Elegance
Aug 16 – Pebble Beach
Aug 17-19 – Monterey Historics?
Aug 25-26 – Indy Grand Prix of Sonoma
Pacific Northwest, BC, Portland historic races
