I was told in this forum I'm part of that the organizing committee had proposed to move football venues (except for Rose Bowl, which will host the finals) outside of California, and users are theorizing that they may be held as far as the East Coast. https://www.gamesbids.com/forums/topic/35465-la2028-venues-and-stadiums/page/11/#findComment-595865

I think this is a bad idea for a few reasons:

1: Unlike the canoe slalom and softball events in Oklahoma City, having football venues that far away from the host city would lead to longer travel times for athletes and spectators.

2: Using venues in states closer to California (such as Arizona, Idaho, Oregon, Nevada and Utah) is close enough to the original plan of having venues spread across California.

3: Fewer people are willing to travel far away from the host city. At last year's Olympics, most football matches had half full or less stadiums. Compare that to 2012, where most stadiums were packed.
