The best way to have a good idea is to have lots of ideas.
I am going to have to remember this idea when we are driving to Florida! I have to be the world's worst traveler so maybe I can use this idea to prevent boredom from sinking in. All I will need is a pad of paper and a pencil and then I will make a list of all the Christmas plots ideas that I can think of starting with the letter "A" When I can't think of another, I will move on to the letter "B" It might sound lame lol, but I have been known to throw shoes in the car.
If it can keep me busy for a few hours, I can't complain. And who knows... one of those ideas just might turn into something.
