Just left Darryl's in my new-to-me red cab, and lo and behold there's another red cab coming down the road, albeit with a braver driver because he had the top down in 52-degree weather. Jim had a good point to put a blanket in the car for the SO.
Saw one other 968 coupe on the way home, somewhere in New Jersey, other than that there were lots of Cayennes and 911's, but nothing else P-car related the whole trip (eg. no 356s, 914s, 924s, etc.)
I did run into more than one zipperhead on the way back, most of them in Corvettes and Mustangs. Typical run-and-gun so they can say they passed a Porsche. So I just puttered along doing the speed limit and smiling to myself.
