I remember there being something like this in San Francisco a year or two ago. It turned out to be a hoax. This would definitely be something to proceed with caution about. That said, how freakin' cool would that be if it is real!!!!
I didn't see that anyone has ever started an Alfetta Photo Thread.
So, since I backed my 76 Alfetta GT out of the garage today and thought I needed a picture of it on the snow in my driveway, we'll see if this catches on.
