The Amalie Arena rumbled with noise from thousands of cheering fans, rattling their noisemakers and banging them against the seats.
The chaotic energy was so loud you could feel the seats shake.
But the Lightning faithful thundered applause not for the team, but for Plant High seniors Brooke Shapiro and Macie Lavender during the first period of the April 14 playoff game against the New Jersey Devils.
The two received a standing ovation for their work organizing the Tampa March for our Lives, which brought in an astonishing crowd of more than 15,000 people including students from 55 different schools across Hillsborough, Pinellas and Pasco counties.
