yea i met with her at the park i did get a haircut but she never visited (did not have sex with her in the hairsaloon)Go on a walk with lisa in the park to meet her, then get a haircut to talk to her more, then she starts coming over to house.
Also, I finally figured out how to get the non-cuck threesome/swinger stuff - I think you have to go to vegas first, THEN go back and do the two skip weekends with Tracy and catch her at the cabin.
