Just got through with doing some things on the internet and walked onto by back porch to get some fresh air been on the porch about 20 minutes and notice the three pulsating lights, then my wife came out and ask what i was looking at and i pointed at the lights when the lights stop,ed an object began to form when it became visible it was gone in seconds first one i have seen that could cloak itself this is not the first i have seen in this spot this but is the only one that i have seen that changed form
