Me and my children were getting ready to watch the fireworks when we noticed an object changing colors and seemingly shape. i called my wife who was only a few blocks away and asked her to look. we both took a video. this lasted for about 15 20 min. we couldn't imagine what it was. it stayed perfectly still and continued changing colors. thought it could possibly be a drone but didn't believe it to be. we watched until it fell straight down out of sight. i thought the whole thing was something cool to witness. about 5 10 min later i went to get my car when i noticed 2 red orbs by the train tracks. the orbs were above to small trees. i put the kids in the car and went looking for them. as soon i i started driving i saw one above the building at south ave field. i pulled my car around, got out and began recording again. as i filmed the one another one came from the southeast, it was only 30 ft above the ground. it barely cleared a house and a tree. it then came towards me and was only 3 4 ft off the ground and less than 50 ft away meanwhile the first one ascended and made o u turn. i could see through the bright light of the 2nd one. it was a bowling ball sized silver orb. the light seemed to be like a curtain or drape. it then went over the football field following the same direction of the first. what struck me odd was that they didn't seem to have a purpose. like they were just looking around by this time i was extremely excited while my kids were scared. the one told me she thought they wanted me to leave them alone.
