I wouldn’t say each residence hall has its own personality, no. Student athletes are only slightly more likely to live in BARH. From year to year, the hobbies and interests of the residents of any given hall vary on a huge scale. It could be that, by chance, all of your neighbors will be into the same tv show and like the same bands or activities. In the same way, you could be a very diverse group of students but still get along. Even if a residence hall had a given personality (say they all like camping) this year, next year it could be entirely different.
