Any college town. The girls are at the age will they will ever look their prettiest, they are young and dumb enough to believe everything you say, very easy to impress, and into casual sex. At the age of 21 they don't know better yet not to sleep with a good looking smooth guy. Nothing has worse decision making skills than a young drunk college girl. A 21 year old drunk girl has about the same decision making skills as a 7 year old with Downs Syndrome.
Once they are 25 you will need a BMW and commitment to nail most girls as hot as the ones I bombed in college -- fashion majors from South Florida-- all ungodly hot and rich. Get em while they are young and easy and haven't been played yet.
