Look closely. That isn't your typical wooden sign pointing to the reception and ceremony. Those signs show how far away this couple's first kiss was, and when they changed their relationship status on Facebook, and where their first apartment was. So adorable!
You need to steal this idea. Even if you modify it. Even if you don't use wooden signs. Maybe you'll use chalkboards inside, or secret spots near windows that direct visitors to gaze outside across the distance and imagine that magical moment when you first met, first kissed, first played foozeball, and of course where you got engaged.
