Just in case anyone else has been looking there is now a Christian school that has a tackle football team in Woodbury, MN that allows Homeschoolers to play. My son is thrilled.
Excellent coach, in the MN coaches hall of fame, many years experience. The boys are all very glad to have the homeschool boys join the team.
There are also two Homeschool basketball teams in the metro area, one on the North side, one on the South side.
