Sping Football I think the KGB Skyshow is always on the first game of the year, which means that SDSU might be the only FBS team to have a higher average attendance for FCS matchups than other FBS matchups.
Last year the listed attendance was 46,400 for the New Hampshire game (though many showed up late, just for the fireworks). Factor in the increased ticket sales we apparently have from the Chargers leaving and the fact that UC Davis is local, famous, and has a riled up alumni community, and we could be looking at 55k.
Hopefully they do something creative with post-Chargers Qualcomm to make it seam less cavernously empty. And less blue-and-gold themed, considering Davis is our first matchup.
