From Portland, take I-5 south and exit at 99W, headed west.  From the south, take I-5 north, exit at Barbur Blvd, then at the stop sign, make two lefts so that you are headed west on 99W. 

At the 2^nd traffic light on 99W, turn right onto 69^th.  Go one block, turn left on Pine, then 3 blocks and right on 72nd.  After 3 blocks, there is a sharp right turn and you are on SW Ventura Drive.  After 1/3 mile, turn right onto the cul-de-sac (after the “yield” sign).  Their house is near the top of the cul-de-sac on the left.
