Ridge Spa, not to be confused with the Sun Spa also on Ridge.  The Ridge Spa is the one on the turnaround and it has a banner hanging on the side of the building along a wooden stairwell.  Don't go up this stairwell, leads no where...go in the back entrance and then go upstairs.  

From my experience its $70 for the hour and tip is never discussed until a hint after session.  A handy is offered and no nudity, however, this could be changing.  I usually see a girl named Judy or Julie.  Not sure due to the accent.  Last time I went "Judy" was busy and I ended up with a shorter stockier girl.  She pulled her top up, but not off and i think she may have put it in her mouth...but I can be sure...she had her head in the way.

Anyway, nice massage and handy and you can get out of the place dropping a 100.
