Bag tags are an extra fun way to add a little competition to disc golf. first you buy a tag. they are numbered 1-30. someone can ask you to play a round with your bag tag on the line. who ever shoots the lowest score at the end of the round, goes home with the lowest tag. when we play bag tag matches, we get together as a group and put everyones bag tag on the line, lowest score gets the lowest tag at the end of the agreed rounds.
