If you're looking for hardcore models, check out some abortion clinics. They are full of women who like to fuck but who are not looking to get prego.
College campus area bus stops. These girls can afford books but could use some help with buying a cheap car.
Dental patients. Their mouth is numb so you can really fuck it hard plus the drool factor multiplies when they can't feel their face.
Dig through sites like this daily:
http://phoenix.whosarrested.com/
Not only can you see their photos sometimes, but they often have other info that can help you locate them through FB etc... Pretty much along the same lines as what HD Content said but without the inconvenience of sitting around in the court houses. The site mentioned above also tells you what they were arrested for and how much they face in fines. They even offer advertising.
