Chem light war stories? I have only one. I was on a field excavation with multiple units on a mortuary complex. We set up a perimeter of chem lights to mark the excavation at night. we were camped close by, and the thought was to warn off any chance ranch vehicle. I woke up at sunrise to a strange noise and a lone figure acting agitated on the site. Thinking we had an upset indian, I woke our native monitor( we were expecting an elder to oversee further excavation and re interment of the remains.) We walked over to find a Basque shepherd, his dog and several sheep fallen in our units.My entire vocabulary of Basco consisted of "hello, I love you" taught by a friend of that ancestry. Remember, signals are good only if an observer sees, and understands their meaning.
