Troop 121 is a strong troop that has part of the Mansfield community for over sixty years.  Troop 121's sponsoring organization, St. Peter's Catholic Church situated near downtown Mansfield, has been a long supporter of the Boy Scout program and enjoys helping the youth of today become the leaders of tomorrow.  The troop has approximately 25 scouts ranging from eleven years old to eighteen years old.

We meet the basement hall of St Peter's Catholic Church on Tuesday nights starting at 7pm.
