At the old Back Fitness along Derry Road (north end of the airport) (I forget the new name of the place) there is a big amazon blonde with HUGE hooters. She is a little older (mid forties) but is actually pretty hot.
Kindof a small "Bunny Glamazon" look.
Sorry but that is all I can remember. Worth a try if you are in the area.
