They were not at a charter school, it was an alternative program public school K-8. Now they are at high school and yes, three football teams -freshman, JV and Varsity, it's one of the three regular public high school in Ann Arbor (although not the one we are zoned for)
Ann Arbor has 3 full-size regular, and 3 smaller alternative program high schools (all public) and maybe 4 charter high schools and 3 private. If we were at one of the alternate public high schools, the charter schools or the private schools, the kids would then be able to be on the sports teams/bands of their zoned school if their school did not offer that program and they could get themselves to practice. So he's be in a green nutcracker uniform instead of Colombia Blue
