One of the biggest and best air shows in the country, the Defenders of Freedom Air Show, is coming up this weekend at Barksdale AFB in Bossier City, La.

The air show is normally held on Mother's Day weekend, but has been moved up this year to Saturday and Sunday, April 21-22. The gates open each day at 9 a.m. and the air show starts at 11 a.m. And the best part: it's totally free!
