I stumbled upon this tonight. As most of the rides are in CA, any comments? http://www.twistypedia.com/roads/usa/
Lots of good roads, but clearly many excellent roads in the central coast area of CA are absent. Lots of those roads are now in the middle of burn areas, so who knows what they are like now. What specifically were you interested in?
Nothing in particular. I’m going to ride the 191 in AZ tomorrow and did a search for it to send details to someone. and there was Twistypedia!
