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

Over the weekend Friday, February 8 to Sunday, February 10, the Gap will be holding training between 8am and 11pm. Mortar training is scheduled for the first two days and demolitions training for the third.

Fort Indiantown Gap is the only live-fire, maneuver military facility in Pennsylvania.

Here’s video from last year’s exercises.
