Last year, I went bye my local BB, Westminster, CA, at 5:30 AM on BF (or GF).
The line was incredible.
Fortunately, it is near a Fwy on ramp and my CompUSA is but two offramps down the line. I was there by 5:45 - line not nearly as long. Through the door @ 6:03 but that which I wanted was already gone.
Actually, I'm passing on Green/Black Friday this year.
I'm giving my shopping list to TCAS and then get the stuff from him on Monday when we meet for lunch again.
