This is surprising to read. I grew up on Fort Ord in the 1990s and we would frequently walk along dirt roads that bordered fences with posted signs warning us of munitions and explosives that could be detonated beyond the fence line. I’ve assumed all of the areas the military tested weapons would have been fenced off! When we were kids we’d go off trail all the time. We just knew not to go beyond the fenced off areas.  And one of the pastimes of CSUMB students is to go “ording,” and explore the old abandoned buildings. You often have to bushwhack between areas to get to some of these buildings. It’s a bit disconcerting to think there might still be areas NOT fenced off that contain explosives. Hopefully that’s just a scare tactic!
