we might do a Griswalds and set the house on fire
rofl my DP informed me last Xmas he wants to do a house with lights like the Griswalds (of course minus the house fire, well at least we have no cat to start the fire, lol)

CQ if it makes you feel any better my DP wanted to ask the same question as we had NO idea how people have the poweroutlets for their outside lights, we too don't feel too secure about leading under the closed window that wouldn't seem closed IYKWIM harr harr
