This season the Cardinal plays USC at the Galen Center on Friday, January 8th. Game time is (sigh) TBS, but supposing it will be 7pm as would be typical, you can sneak out of work early on the Friday afternoon, catch a 2pm AA flight or a 4:10 Southwest flight at SJC, grab a rental car and be at the Galen Center door in plenty of time. Well, enough time.
Once there you can see what kind of team the troubled USC Athletics administration has managed to scrape together (read Bob Kinder's analysis for the juicy details).
You get all day Saturday and Sunday morning to live it up in the greater L.A. Basin. What will you do with the time? Share with us in the comments, please?
The UCLA game will be on Sunday at (you guessed it) TBS o'clock 2 PM. Supposing it will be the typical 1pm, you can catch a 5:25 Southwest or You should be able to make the 6:45 AA return flight—but don't book this flight until the game time is announced. If there was a late decision to put the game on TV, the start time might be later.
If you would rather drive (the Travel page talks about the fly-drive trade-offs), you can schedule a leisurely start Friday, go down 101 with a lunch stop at Pea Soup Anderson's in Buellton, or someplace in Santa Barbara. With two drivers trading off the return trip up I5 can be completed on the Sunday night.
