I was NOT happy with how this cake turned out. I originally made the sides with color flow, but didn't allow them enough dry time and they broke. At the last minute I covered cardboard with fondant for new sides. It was so heavy we had to support the sides with toothpicks. The tires were doughnuts, and the dirt is chocolate milk. Even my lines were crooked! I hope to redo this cake someday and have it turned out like I originally planned.
