There are plenty of hot, [white if that's your desire], sorority girls in and around big cities as well, you don't need to be in TaMU or Tallahassee [been there] to find them. I've picked up dozens at bars and coffee shops/etc over the years and as Franco said, away from social circle it's not hard, just game as normal, go for instadate, get the #.
Very many, if not most of them, are looking for deniable dick outside of campus/social circle. My first experience with this as a much older guy was chatting up this cute sorority blonde with a 9/10 body [athlete] at a bar, we hit it off, made out, drove her back to her dorm 30 minutes away. She would take the train in to see me 2x a week. Her prior bf had graduated and left town. There's no difference btw these girls and any other cute girls if they're not with their social circle, none, nada.
Girls can easily tire of the whole Greek system even if they're inside it. And a guy that can get them a drink that's not a Natty Light goes further than you might think. And, let's face it, 20 yr bros don't know how to do sex correctly. And an older man with a real life, career, etc is a catch in their eyes. They're not even looked for a totally ripped guy 95% of the time, that makes them feel insecure about their body, just a regular in-shape dude is fine.
