Bishop Garrigan High School

Bishop Garrigan High School is an all-boys high school which has maroon and gold as the official colors. It's only in the original online version and it's mentioned that Dan, the son of Frank's boss at work, Mr. Swann (called Mr. Warren in the books and the movies), goes to the school. Greg acknowledges that Bishop Garrigan probably is a good school, but his issue with it is how it's a boys-only high school.

Frank was planning on enrolling Greg at the school once he got done with middle school, but while waiting for Bill Walter to move his van, Bill noticed the folder in Frank's hands and revealed he's a former student at Bishop Garrigan High School—Frank was shocked by this and ultimately decided not to enroll Greg at the school.

Trivia

 * It's possible that Bishop Garrigan High School is a private school, since it's mentioned to only accept male students—even nowadays, many private schools (particularly religious schools, boarding schools and/or high schools) still only accept either male or female students.
 * Also, assuming that it is a private school, it's also possible that it has a uniform policy (or at least a very strict dress code), as many private schools typically have uniform policies.
