The Charter Oak High School football team has agreed to play a home-and-home with Orange County power Los Alamitos, starting with a road game against Los Alamitos at Long Beach’s Veteran Stadium this fall.

Since moving to the difficult Sierra League and Inland Division, the Chargers have increased their quality of opponents in nonleague, and this might be their most difficult non-league schedule ever.

The Chargers will face Los Osos, Corona Roosevelt, Glendora and Los Alamitos and Bishop Amat in back-to-back weeks (Week 2 and 3). The Chargers will take on Bishop Amat at home following its road trip against Los Alamitos.

“I know what’s going on in the heads of our kids,” Chargers coach Lou Farrar said. “It’s a (daunting) schedule, but if we want to get past the Upland’s and better teams in our division, we don’t want the stage to be too big for our kids, both from an emotion and physical standpoint. I don’t know if there is any other way to be prepared for our league and division without playing teams of that caliber in the preseason.”

Los Alamitos is from the Sunset League and was 6-4 last year. The Sunset League is moving from the powerful Pac-5 to the Southwest Division. The Sunset League includes Newport Harbor, Huntington Beach, Fountain Valley and Edison.
