The person I made this cake for owned a Harley.  The motorcycle was a toy.  I shaped fondant to look like the Harley symbol and wrote Happy Birthday Gene.  Gene was also turning 50, so I made the speed limit sign reflect that.  I put fondant flames along the bottom and used food glitter to give it a special ‘burning’ look.  The hill was made from cake also.  I placed the bike to go down the hill since he was turning 50.  Everyone loved it.
