This is from the Cars cartridge. The challenge was to use your least favorite or least used cartridge. When the Cars cartridge came out I just thought I had to have it because I was sure I would use it a ton because I had a little boy. I had yet to use it. So I pulled it out. I decided to make this particular one because we seem to be running around 100 mph. So this is just a reminder to slow it down and little and enjoy life!
