Take I-5 south from the bay to over the grapevine. Watch out for the CHP around Los Banos and south for about 50 miles. Merge on the I-210 east towards Pasadena. Merge on the I-10 east towards Ontario. As you pass the I-10/I-15 interchange look for the track on the left.
Mileage one way: 500. Time: 4.5 hours - warm them turbo's :)
