Ouch!

Hertz to 105 East:
> (If you exit by the entrance, turn LEFT at Aviation).
> LEFT at Arbor Vitae (also true if you exit by the Gold parking stalls).
> RIGHT at Aviation
> LEFT at Imperial Hwy
> RIGHT at entrance ramp to 105 East.

You are arrive at the peak traffic time. I would go insofar as taking the 110 North carpool lane and exiting at the 39th St. exit (Adams can get VERY backed up, and the signal lets like 4 cars through).

From 110 Carpool Lane:
> Exit 39th Street
> LEFT at light (39th)
> RIGHT at Figueroa (note, there will be a "carpool lane" on the far right that nobody uses. Watch for parked cars).
> RIGHT at 6th
> LEFT on Olive (you'll past Grand).
> LEFT on 5th.
> LEFT on Grand, and you're there.

Also note, the above directions will take you past my alma mater
