If you're looking for something more than a strait away cruise, then this is the place for you. Turnbull Canyon is in San Gabriel area in southern California. Not much of a long ass trip or what not, but definitely a fun drive. Technically, it's about 4 miles of twist and turns, but usually it's so fun that i end up bustin a bitch at the end and doing it all over again. The only downside about this place is at night, drivers use the road for racing and drifting... often carelessly. So I'd say watch out.
