I observed 2 glowing yellow/orange orbs gliding above the tree tops. they were traveling at what i would guess was about 5 or 6 miles per hour. (i feel as though if i had sped up to a fast jog i could have kept up with them for a while) one of the orbs was approximately 20 to 30 feet behind the other. they were not attached to each other and they were silent. i watched them as they traveled westward until i lost sight of them because of the density of the trees. i am not absolutely sure of the date but i'm guessing september 2nd in the evening. i did not have my phone with me so was not able to try to get a photo. it is when i described this episode to my sister and nephew today that they thought i should report it to the mufon website.
