There are a few SP who advertise on BackPages. These are generally girls who are touring in their early 20s, and I suspect most of them have pimps.
There are a few local Milfs including the very tattooed Camilla Moon and the poorly reviewed Kathy and Terry.
I am not aware of any MPs in Woodstock.
A few miles east of Woodstock on Hwy 2 you will find Nikki's Roadhouse. This strip joint can be a lot of fun but it is a dive.
