Anytime you send electricity via an extension cord from the inside to the outside, the outlet you use should be one with a GFI.

Having said that, I just realized my wife, for the first time, added Christmas lights to the bushes in our front yard and used an extension cord. My next stop is at ACE Hardware to buy a GFI outlet!

I believe you are incorrect, ALL of the outlets in our garage are protected by GFCI either outlets or circuit breakers, this is a building code requirement. Several of the big box stores sell power testers 9these indicate power and co0rrect wiring) that have a button to test GFCI operation, I will guess if you get one these you will find that your garage outlets are protected. Also, if you add a GFCI in series with another GFCI BOTH may trip, so IMHO, test first otherwise you may need the electrician to find the 'other' GFCI.
