I catch up slightly and realize I'm following a new Nissan 350Z who, like me, is looking for the best lane to take transitioning onto C-470.

I follow, thinking, "Okay, time to get outta my way, cuz I love these turns!" Then I realize that he is not breaking but instead speeding up where I generally start cursing into my helmet as I see brake lights in the fast lane and I barely lean in for the first of the two sweepers. Zowie! He wants to play! Of course, being the toe-dragging speed monkey that I am, I sped up right along with him!

Before I know it, we're both cruising through the second turn at what I estimate being 85MPH (I know, Bandit12, that's not fast for you, but on concrete, with fully inflated tires, and in the dark, and I was not about to look at my speedo), a turn I can take on a good day in a normal riding position at 75. There I was, maintaining at a constant distance from the tail of the blue-halogen-headlit sportscar all the way through the turn and then some.
Some time down the road after we both mellowed for the straights, he slowed to let me pass. I gave him the thumbs up and smiled as I took a slight lead, though neither of us vying for position. As luck would have it, as we passed the Morrison Road exit, he, too, was headed up the canyon! He let me take the lead but followed at a safe distance. I took it easy going up the canyon (a pretty constant 70, for me) and either he took it really easy, or the Z doesn't do the tight turns as well. We ultimately caught up to a traffic cluster and had to slow for the last mile before my turn. As I signaled and pulled into my turn lane, he flashed his brights and I waved. Hmph! Cool!
I still wonder if he noticed that I'm a girl! (Wearing my bulky cordura First Gear and my tailbag strapped to the luggage bars - it's a little harder to tell!)
