Black Friday Store Hours 2010?

Black Friday began on Thursday in many cities with some stores opening their doors on Thanksgiving Day.
I know many stores were already offering Black Friday deals online but the best deals are in the store. What are the Black Friday store hours for 2010?
What time will Walmart and Sears open? Will they offer good Black Friday deals?
Any advise for me to get the best deals?

It entirely depends on the retailer. Some places open at 10 pm tonight, others open at midnight, others at 2 am, others at 6 am, others at 8 am.
Also, as with every chain store, hours can vary depending on your location. If you want to be sure, call your local store before going.

Here's a list of the most popular stores.
