Thanks everyone
I've floated the idea of doing chili lights before. http://www.jehovahs-witness.net/jw/friends/204458/1/Question-on-Christmas-Lights
They're the same idea, but they have nothing to do with the Christmas celebration. (The concatenation between electric lights and Paganism has always seemed a little weak to me, but I'm assuming the JW objection is to the actual Christmas celebration and not to electric lights per se.)
Anyhow, I asked her if that's what she had in mind and she said, "I like the icicles too." --So be it. I aim to please!
