I was at my kids swim lessons at at a nearby city outdoor pool at 7pm. my son was in the water and my daughter was sitting with me. i noticed a yellow helicopter circling the area then the pool area a few times. after it flew off,sw, i looked up and saw what i thought was venus. went back to watching my son. looked back up and noticed the object had moved. started looking closer and noticed there were several other faint sphere like objects. they seemed to be floating in formation slowly descending. as they moved overhead it looked like they where connected by cables? by the speed i thought maybe they were balloons? they stayed in perfect formation going in a perfect straight line almost due e to west. i pulled out my phone and snapped a few shots and a short video. my daughter asked what i was doing. i pointed out the spheres and she saw them too. i looked around and no one else seemed to have noticed. we watched them until our view was blocked by the pools privacy fence. this all took place between 7 to 730ish pm. blue skies with some haze. the sun was behind us. we thought it was cool and joked about seeing a ufo. seemed weird that no one was paying attention. when i got home and looked at the pics i was disappointed with what the phone's camera captured. showed my wife and son but they were unimpressed. this was 3 months ago but the 'what is it' question started driving me crazy... note not able to upload vid.
