At the track where I used to race at, every couple months they would hand out sheets of paper with the track boarders and everyone who wanted would design a track, or two or three. Then they would set them all out on the pit tables and everyone would vote for two. The top two would then be voted on once to determine a winner. One of my designs ended up second once. The winner also got a prize but I don't remember what.

I will go for #4.
