Chris and I went to a C&C yesterday. Great turn-out for the end of the season with 40-50 cars there, everything from a Model T touring car to a bunch of Porsches to a couple of Ferraris (and one Alpha Giulia, for Mr. Gryzkanowiscowski-xyz -- Nice paint, BTW, Marty)
I was parked just behind one of the 911s which happened to have a 2" PCA sticker in the bottom corner of the windshield - same place I have my Clown sticker. People would look at the 911, then wander back to Pearl and do a double-take at the sticker and laugh like hell.
I love it.
