No plans for the weekend? Craigslist to the rescue:

I am a female artist and model and i need someone who has no inhibitions and wants to do something a little crazy. I want to rent a horse in central park or van cortlandt park in the bronx (Wherever they let me take it free roaming)

I want to ride full speed through the park topless on the horse and I need you to shoot it. I want not only the shot of me on the horse-hair flying, boobs getting air time , etc... but I want peoples reactions as well.

I will be a blur of nakedness and horse and i will be gone before they have the time to process what they just saw. it will be great and i think it will make for a f*cking fantastic photo/video.

... No freaks.
