Kinda bummed about Pepperdine. Just spoke to an admin a week or so ago. No softball in the future for them.
USC has no room, however with offsite setups could work out ok. Just have to find somewhere.
There is room at Expo Park for USC to put a softball facility
Or
The soccer and lacrosse teams can play at the new soccer stadium at Expo Park and USC can convert McAllister Field (which is also off campus) in to a softball field.
UCLA plays football games at the Rose Bowl, 26 miles from campus. They also play baseball at Jackie Robinson field which isn't on UCLA campus either.
Another So Cal school I don't understand not having softball is UCI. UCI is the top school in Orange County, the same Orange County that Batbusters and Firecrackers as well as PGF calls home.
IDT may be in Boulder but PGF is in Irvine and UC Irvine doesn't have a team.
