Is there a way that we can distinguish ourselves as we walk around the games? It seems that no matter what times what days, not everyone will be able to make it. How can we let each other know that we are Xmarkers from a distance? This is my first Grandfather games and I am anxious to make the most of it. The family (minus the wife) and I will be camping, so we plan on taking in the whole experience. Just let me know what I need to wear to make my self noticed by fellow Xmarkers. Thanks.
