I would recommend visiting their website:
https://gateway.usarmyjrotc.com/http...c.com/jrotc/dt
and using the "contact us" button to find out. I would think that they would investigate how many folks want to become cadets and make a descision on starting a unit there. If there are not enough they (and I would) most probably recommend attending a nearby school's JROTC program (if theirs is after school.)
Good luck to you, and I'll meet you on the High Ground,
