If you hear some loud booms this month, worry not: It’s just the Gap.

Fort Indiantown Gap is the only live-fire, maneuver military facility in Pennsylvania, and the training ground will be active every weekend during March.

Demolitions training is scheduled for March 1-3, March 14-17, and March 26-27. Artillery training will be held March 6-10.

Here’s video from last year’s exercises.
