Like a lot of old timers here, I have a lot of fond memories of racing at Fort Hood.
But I don't see TSCEC getting involved here, at least initially. It's going to take a grassroots local organization getting together to make a proposal. First getting some trails open, marked and established, then evolving into some organized races.
TSCEC is only series organizer; the races themselves are put on by local clubs or organizations.
I'm not aware of any authorized riding areas on the base, sad to say. Back in the day, for races anyway, it seems we rode over large areas of the base.
