Inspite of the pictures, I've never met a girl at a suburban amp younger than forty, except for one near the corner of Coit and George Bush, which no longer wants reviews. The AMP's in Dallas often have girls in their late twenties. The only point of the suburban amps is their deniability factor, i.e. "legitimate" massage. If you get caught there, you can claim you are getting a message. You can make this somewhat credible claim to either the cities finest, or to your lovely wife. As to which places are likely to provide extras, the pictures in the ads are more code than reality. If they provide three pictures of random asian models in skimpy outfits, they probably offer at least L1.
