If a fellow DISer wears the green ribbons displayed on his person, or if they wear a DIS shirt, I will probably see them. I wear them myself and I am always on the look out for others. On all trips but one, I have been spotted. Every single time, someone saw the ribbons tied to the back of my waist pouch, not the DIS pin worn on my blouse, or they spotted the DIS t-shirt, also from the wording on the back. I'll be there this coming Wed. thru next Monday - look for me!
