Troncones to Taxco

I took the road from Altamirando to Troncones in 2010 and was chastised by several Mexicans for disregarding safety. At that time, it was mostly unpaved, and often single lane. I doubt it has changes much . That was 9 years ago, but I would not do it personally. I suggest driving to Pie de La Cuesta north of Acapulco, spend the night then skirt Acapulco on the way to Taxco.
