A t-shirt idea for RAGBRAI. Thoughts?

I wanted to design a t-shirt for off-bike time a day or two during RAGBRAI.  I had plenty of ideas but many of them would be in violation of copyright laws for using RAGBRAI or Stand Up to Cancer logos.  Then I had an idea to make a cancer ribbon out of a bike chain.  This proved harder than I thought it would be.  I needed a vector image of chain links so I could make the ribbon and enlarge it to avoid pixelation.

This is what I have come up with.  What do you think? 

 

 

I'm not actually AT $10/mile yet, but so close that I'm sure I will be by the ride, thanks to the many generous donors.  I am truly honored.
