How about printing up a very brief intro to the Terri Schiavo case, along with a pointer to the Terri's Fight website and possibly Free Republic? It could be done on half a page. Attach them to the balloon string. Might generate some interest from those who find the balloons later.
EXCELLENT idea FatherOfLiberty!!! Perhaps someone could send a " sample post" that we could print and add. We could put it in a plastic sandwich bag and then tie it on the end....I am thinking I will do this.
