As you note 45k is a reasonable number to shoot for.
However this will require a break in normal patterns. And this games import is off the charts not only because of the obvious 6 win bowl plateau but because of the Dino factor. This is the first time I'd imagine he's gonna be looking at support as a true bell weather as to what's possible here. First Saturday night game in almost 10 years I read.
We need to pull out all the stops at every level of interested parties for this one. Again break from the routine. For example In the attempt to avoid crying wolf I only engage and encourage the casuals in my sphere at times like this. Hectoring them with texts and emails. Buying 5 extras this week to give them away, if every regular can bring just one extra person we'd be there.
Similarly I'm wrapping up at our usual fine mess tailgate an hour early and will encourage all others to do the same, get in there early to start creating atmosphere and let Dino and the team for the FIRST TIME see the place packed and already rocking as they enter.
The university need do the same as they may already be with ticket deals/the quad experience, but also do more to think outside the box and do things like to create atmosphere and, for example, consider lower the lighting for the now televised walk out of the locker room to the field as they then run out onto the dome field, advertise this, and other, atmospheric enhancements, give away Otto bobble heads, etc.
The city too, what a perfect opportunity for the new mayor and new county legislator to make a mark and hype up this game/event with some PR and a couple of unique events city and county wide.
Whatever it takes man, pull out all the stops, speak in cliches, who cares, just do it, them and all of us. Game on, let's do it...
