I can't remember...when does SPN return???

[growyourwings]

    Running between mutliple appts tonight (kids, etc.)  Does anyone know what date SPN starts back up?  I just heard back from sister-in-law #2.  I lent her SPN season 1 and she watched all of them in one day.  We're trying to plan for her to come over to catch up on all the SPN season 2 eps I have on my iPod.  We want to plan it for before season 2 starts back up--but I can't remember the date!  I keep confusing it with Battlestar's return date.
