I don't do a huge display - just a couple spools of white LED lights from Target, but my house is fairly small. I just do the fence, the columns on my front porch, and outline the roof. And I don't have outdoor power either, but I have a window with a big hole in the screen and I just run the cord through and under the window. Last year, though, we had about half the block decorated by the end of the season - it was very cool to see and fun to have started the trend! Especially since I live in sort of a low-income area - I'd rather see "tacky" (cheesy holiday displays) than sketchy houses that look half-abandoned in winter. And the more people had lights up, the more people decided to decorate.
