There was a touring wonder girl making a loop of several states, advertising on backpage and posting here. She had several very good reviews. I scheduled an appointment with her.
I'd rate the experience a 2 on a scale of 1 to 10. I got the feeling she was there largely as a casual observer.
Here's what I learned: She was a newcomer conducting the tour to earn money to pay off a loan. Apparently, she had met her goal. I saw her on her last day -- she was on her way back home the following day. She's returning to a "normal life" (no more escorting).
She may have provided some good companionship in order to get a few good reviews. When I contacted her, she directed me to those reviews. But it was the end of the trail for her, with no incentive or need to be concerned about good service or a good review.
The moral of the story: Stick with established, reputable, providers. And if you DO decide to visit a touring new provider who's only been around for a short while, hope that you don't see her on the last day of her tour.
