My dad was in a similar spot (zero prior connection to the school, although I'll drop a funny story below) and became a fan very quickly - we always bonded over sports but Georgia Tech football in particular was a special one. Not sure how local to Atlanta you are, but getting to a game at Bobby Dodd is a must do. There's so much history in the stadium and the skyline views are impeccable and unique within FBS - try to make it a night game if you can so you can see the Midtown/Downtown skylines lit up although it can be tricky to predict that given that game times are mostly announced a couple weeks in advance. The State game will be at night and probably great weather.
As for the story, we had a slight connection to Tech well in advance of my admission - my mom taught math and attended a professional conference in downtown Atlanta. My dad loved football but at the time was more casual about the college game (we are from New England) but still had somewhat of an affinity for Georgia Tech probably because of the national championship team in 1990, at-the-time successful George O'Leary teams, and probably mainly Bobby Cremins' basketball teams (who he excitedly got to meet in the Callaway Club a few years ago before a game - talked Bobby's ear off hah). He enlisted my mom to bring home a Georgia Tech sweatshirt from the bookstore, however my mom must have not totally understood the memo because she trekked through downtown Atlanta and brought home a Georgia State sweatshirt

. He wore that sweatshirt constantly for well over a decade until it was fully faded and worn in, but we made sure to finally get him his Georgia Tech gear when they dropped me off for the start of Freshman year
