Turk,
Having been born and raised in the South, I can certainly understand your concerns with the colder (below 70) weather. Don't let these guys give you a hard time. The other day it got down to 60 degrees here at home (!!!) and we had to turn on the heat!
Seriously, shortly after the Miata came out (back in 1991), my friend and I decided to take one for a test drive. It was January. It was really cold (like 35 or 40). We just dropped the top and turned up the heat. What a blast!
Got any more Cobra pics from your weekend?
