 If you've been out to a high-explosive field site and you go out there on shot day and it rains, well, you get to go spend the next couple days at the hotel room until your next shot day comes up. This is true. So here at ERDIC, with the blast load simulator, we shoot every day. It doesn't matter if it's raining. We're inside the underground enclosure. Basically, the only days that we don't shoot is when there's ice or snow on the ground and ERDIC shuts down.
