I agree with the above post.
That said, I have been to this area once. The "twisty narrow roads" are precisely the reason cyclists want to go on them. There is a lot of climbing and when I was there, the Tour of Missouri had just come through the day before. It was beautiful country, so why wouldn't cyclists want to ride there? It's the same reason that area bike clubs and people who live in the city come to the area where I live to ride on the same type of narrow twisty roads. There's been some tension between riders and drivers, but mostly, I have to say it has been because of poor rider behavior (riding 2-3 abreast where signs clearly prohibit it). Not to say there aren't idiot drivers here, because there are, but there are also so many cyclists that the level of awareness has been raised.
