As the crow flies, I live about 15 miles from Camp Lejeune. When they have bombing practice it's very strange. If you are outside, you rarely hear the explosions, but if you are inside, you can feel them, like during a thunderstorm and the bass of the thunder is so low it vibrates your house. They announced today that they are also clearing out unexploded ordinance on a nearby island (used as past bombing range). That might be what they are doing now, I can hear them outside. They were going to blow up 2 700lb bombs and a bunch more smaller ones that didn't go off the first time.
If we ever have an earthquake, I'll miss it thinking it was the marines and their toys.
