The Bomb Squad Is Parked On Our Cul de Sac

I'd post photos but it's dark out and I can't figure out a way to take them without being obvious. No crime has been committed but a very nice police officer knocked on the door and told us our neighbors found a pile of old blasting caps while they were demolishing their carport. The police have assured us that they're pretty old (like 50-60 years) and hold no more charge but as a precaution, they called the bomb squad out. We don't have to evacuate.....yet.
