Apparently, there was a 5 minute Australian Football match staged in Denver, Colorado during the halftime of an Association Football match recently. The potential audience was ~ 13,000. More info/picture(s) here. https://www.bigsoccer.com/forum/showthread.php?p=2860159 I think such promotions of the sport, taking advantage of an already assembled crowd is a great idea.
Thanks for that, Chandu. Looks like it was a fairly decent exposure. And AndyMead took some pictures as well... This from the linked thread... Looks oddly like the Western Bulldogs vs. Melbourne. Wonder if he and/or Wade took more photos of the halftime event...
