My eldest loves football. Unfortunately, he is attending a private high school that is too small to field a football team. Does anyone know of football programs for high school kids that aren’t associated with a school?
Check with the local public high school. Some places allow for non-students to play. Locally we have a charter school (not private, but still) that doesn’t have a football team. Some of their students play for the public school team. Conversely, they have a hockey team while the public school doesn’t and a few students from the public school play for the charter school.
Sorry for getting back so late, but thanks. I should have time tomorrow to drop by the high school and ask.
You can always call them up, instead of dropping by (although I’m guessing in Bubbaville, it’s not much out of your way ;)). Most high schools I’m familiar with that are large enough to field an 11 man football team have an athletic director. If not, there’s most certainly one at the school district level that can help you.
FWIW, I was on the high school wrestling team in high school, but there was also a club that was not affiliated with the school program. We wrestled scholastic (aka American or folk style) with the school team, and Greco-Roman and freestyle with the club.
There’s also a high school rugby club in Albuquerque that’s comprised of two or three high schools, because they don’t have the interest or support of the schools to have it be directly identified with the schools. This amazes me, because Santa Fe and Los Alamos, which are both smaller, have huge numbers coming out for both boys and girls high school rugby.
Do high schools let adults that aren’t parents just “drop by”? I would think you would, at the very least, have to make an appointment. 
Most states allow home schooled, charter schooled or even competing school students to compete for nearby schools that have a sport or activity they do not have. Often the rule is if the school or student is within the district boundries or abuts the school school district’s boundries, then the student may compete for that school district if their own school does not have the sport or activity.
I remember I did a story on a young woman who played golf for a school within a school district next to their own. I also did one for a home schooler that did similar.
There occasionally (possibly often) is resentment towards the student coming in however. Because if they are good enough, they could well be bumping a student that is actually from the school for a position on the team.
