Wow... I'm in the Tally area on a regular basis and in over seven years, have only seen one Alfa. It's hard to fill my Alfa fix when I'm there. Your car looks great! Hopefully those attending knew what you had and appreciated it.
Amazingly that's just a reflection of the sky on my Lemans blue paint. I am still sporting non-traditional paint colors though, in the form of Italian stripes on the lower half, put there by during the car's SCCA days in the late 80's
