My girlfriend and i were driving east on fl-60 around brtow. we both noticed two lights to our upper left (northwest). the upper light remained constant white while the lower light grew larger and changed colors from white to red and back. after about 45 seconds the top light faded away as the lower light exploded into 10 or so smaller pulsating green and red lights, these 10 quickly multiplying to a max of 100 or so within a minuite. all of these smaller pulsating lights seemed to be floating independantly of each other and constantly changing directions. this continued as the light spread out, falling towards the south east. during this directional elevation drop, 2 or at most 3 of these lights burst into flames with tales 50 times larger than the original light. these flying balls of flame were zig-zagging abruptly and seemed to be so close to us, almost coming in our direction. one of these flaming lights dropped so close to the road i thought we would surely drive by the fire it caused. by 6 minuites the lights had completely disappeared below the treeline, looked like they couldn't have been more than 200 yards away. i am still shaken up by this and won't be able to sleep tonight.
