Winding, Wow!

May I suggest:
- involve the Indiana Cycling Coalition - notwithstanding the organized event, you still had rights to the road...and as long as you had lights, I'm sure you were operating within the law.

- involve local media - while I agree with Zen, if you don't have 'footage', it's time to get some airtime

I also encourage you to sit down and write every detail...may be helpful later, OR it may be the catharsis to helping you resolve this issue in your mind.
