At first, i presumed it to be a large plastic bag floating by at about 500 feet. that in itself is unusual. superstition mountain is nearby and does create some weird wind updrafts. i grabbed my canon and began taking pics. it remained at 500 feet and it was traveling northward. that is unusual because most wind travels towards the east here. so i had to zoom to get closeups and that is why some of the pics are blurry. i was going to blow it off till i examined the pics. it does constantly change shape. upon examination of the pics, i saw very unique features. at first, it does look like plastic but there are too many edges. there are also linear features that look like ridges and structural shapes. i also noticed a dark human-like shadow in the middle in some of the pics. there are some reinforced edges as well. it is not at all like any reported ufo's but i thought i would submit it, and let you guys decide. check the pics out closely. thanks!
