My gf and i had walked to the library here in belle chasse to use the wifi so we could download music before our walk. its a nice clear night and the first real cool night of fall. our bluetooth headphones went out and as we checked to see why, we noticed the busy traffic on hwy 23 suddenly got quiet. i saw this glow out the corner of my eye and looked up in time to see this perfectly silent triangular craft.,which was moving in almost a dreamlike and errierly silent way across the sky about 150 feet over our heads...Right above the telephone pools (maybe 1 and a half lengths of a telephone poll up) and took a sharp turn in a direction which follows the mississippi river south from where we were standing. this to me is the smoking gun....I've seen some weird shit in the skies but nothing as otherworldly as this. to me there's absolutely no doubt. my girlfriend was equally as floored by this event. after this event we kept hearing multiple car alarms going off in different areas of our town. also when i tried to get a picture on my phone, i couldn't get the screen to come on.As soon as the event was over we were both able to get into our phone
