The GeoDeck is the recently reopened observation deck on Reunion Tower. Dude Perfect is a mildly obnoxious group of frat-guy types who have achieved Internet fame filming themselves making improbable basketball shots. How it took until 2014 for the two to come together is a mystery, but it finally happened back in January when a basketball was hurled from Dallas' most '80s landmark into a hoop in the parking lot below. After all, the land around Reunion Tower isn't being used for anything else.
