Don't feel too bad, I just clicked the NE link instead of the PacNW one.
Anywho, take I-5 south to exit 151 and go west...past Int'l Blvd. and down a steep hill. At the bottom of said hill, you will see a golf course on your right (directly under the flight path - GREAT spot for a round). Across the street from the golf course is the lot for SST. Ride from parking lot onto paved trail which, in turn, will lead you to singletrack and eventually flowpark, etc.
