Or just check stubhub.
New Orleans, LA, Providence RI, Oklahoma City OK, and San Jose CA are the Thursday/Saturday sites.
Spokane WA, Buffalo NY, Jacksonville FL, and Milwaukee WI are the Friday/Sunday sites.
Salt Lake City UT (West Regional) and Syracuse NY (East Regional) and Thursday/Saturday sites.
Houston TX (South Regional) and St Louis MO (Midwest Regional) are Friday/Sunday sites.
Indianapolis, IN is the Final Four site, and is of course scheduled for Saturday/Monday.
BYU's biggest homecourt advantage would likely be San Jose, as it's closest (and NorCal church membership is probably the largest of the four sites...)
:P
Being completely selfish, however, I'd be able to watch the games if they were in Rhode Island and Syracuse...
An 8 hour drive from DC is doable, but don't think 18-20 hours to Louisiana or Oklahoma is...
Was awesome only driving 3 hours to Philly last year (except of course for the result). The previous time was a LONG drive to Lexington (funny, though, the result there wasn't much better).
