You have to go to Moorpark College to park and ride a shuttle from there. There are very many people waiting, and the freeway may be slow (according to the speed map, currently less than 4 mph near the Madera exits).

My daughter and I got up at 3:00 a.m. and went over to Moorpark College to catch a shuttle to the library. We never found the end of the line. It's a three hour wait from the time you enter the parking lot where the shuttles pick up passengers, and a guy sitting there on the steps said that the line to get to the parking lot was four hours (at 4:00 a.m.). Peoople were pouring in, and the 118 coming from LA was a complete traffic jam. Recommend the 101 to the 23 to the 118, if you want to stand in line 8-10 hours just to get on the shuttle.
