Me and my mom were driving home from scouts near the saint Phillips inn area, we turned onto the road that takes us home and opened the sun roof, because it was warm. I pointed out something in the sky to my mom that appeared stealth bomber shaped. She looked. It was also going quite slow, slow enough not to be a plane. It was shaped like a triangle but with a little triangle cut out of the back. It also had orange and blue pulsating lights. We continued to drive looking at it. It was dark but we could see the outline of whatever it was by the lights aforementioned on it. It made no evident noise. We were tired from a long day and did not desire to pursue it. We were driving west along the road as it was going in a straight line north east. We stopped for a second and watched as it disappeared over the tree line. We were generally shocked. I tried to get my iPod out to tape it. It did not get any good tape of it. We continued on home and that's it. The closest big city was Evansville but the closest city was Mount Vernon .
