Okay, so it's technically not moss on the car, but this picture does get several comments, mostly “How did you do that?” and “That's not real, is it?” Yes, it is real. And that is the real picture; it hasn't been doctored at all.
So, how did I get that picture? Well, I went with my friend Greg to a local junk yard and happened to have my camera along. This car was perched up on a rack, covered in ivy.
