Angeles Forest Highway (LA County Route N3)

[Max Rockatansky]

The hardest part of using N3 as a shortcut is the slog on CA 2 north of I-210.  The climb out of La Canada Flintridge is slow and often has obstructing vehicles.  N3 itself is fine, I've never had difficulty passing or maintaining speeds above 50 MPH on it.

^^^ not to mention the slow vehicles in front of you followed by a convoy of ricers on your ass.
