I was standing in the street getting ready to get in my car, i looked across the street and in the driveway i seen heat waves in a localized oval shaped area 34in x 20in 2 feet off the ground 20 to 25 feet from me this went on for about a 1 1/2 min. i was thinking about going over and touching it. when i started for it the heat waves stopped and the area filled with hundreds of little vortexes. this went on for 30 seconds or more then the vortexes like sucked in a dark smoke it happened in a second. then it stayed where it was 2 feet off the ground for another 20 seconds with the dark smoke swirling in side of it. then out of the front part of it (a leg i guess you would call it) protruded out of it. then it planted it on the ground and a protrusion came out the back side, and it ran like a dog across the street in front of me. then ran down the sidewalk for a block and a half out of my sight. i can show you where it happened on google earth street view and draw a sketch . im not sure what it was to me i think that's how an advanced civilization would send something. or im going mad. i was not drinking or using drugs it was daylight no swamp gas, i know what a dog looks like it was no dog, i could be seeing things. i can't prove it and i cant find any thing like what i seen on line.
