On 5/12/17 we were coming out of big bend national park, tx. we pulled over on the side of the road to watch the moon rise.-10pm.Ish no moon yet. while looking over the field with my night vision binoculars,i saw the 1st orb about 40 ft. away. it was about 4 feet off the ground and kept going behind the bushes/brush when i shined the ir-flashlight on it. i thought it was a reflection from a deer's eye because when i looked without the inferred-binoculars(naked eye) i couldn't see anything. it was a big white ball that was reflecting the ir-light from my binocuars and my hand held infer-red flashlight. i watched it for about 30 seconds. then my friend said "what is that?". i turned around to see a bright green orb approach us from the west about 50yards away. it stayed about 6 feet off the ground and moved slowly towards us until it was about 10-15 yards away. then it stopped for about 15 seconds. it didn't move and never made a sound. we just stared at it asking each other "what is it?". then it slowly moved north in the middle of the road for about 30 seconds till it disappeared. it never fluttered or blinked. both orbs were about the size of a big softball. we just stood there kind of confused. we weren't frighted at all and i had my gun on me. i still don't know why i didn't approach it. it's not like me to not have gone up to it and try to touch or investigate it. i plan on going back out there in a few days(june,19-22. 2017) to see it again and try to make contact.
