Name Ashley B
Experience Level 1/5
Remarks I asked another group walking a dog if they saw it. They said yes but thought it was a firework. It was not a firework. It was to high and fast. It seemed to head NE and burned out over the lake. I am not totally sure on the time but probably between 11:30 P.M Central and Midnight.
