In our area this yaer there is a new Xmas display sold in stores for about $19. Its a sign, looks something like a yard sale sign, but very nice. Says Merry Christmas, and then below it number of days till Christmas. Its battery operated and has a bright red LED display, basicly a count back timer.
Couples could do the same thing, put the couples logo and name on it, maybe a phone number, and it could read how many days till we go back home.
I would buy one.
