Re: Floating garbage bags
Pretty much as soon as I had it in view of the binoculars. Easy to see by naked eye shortly after. At least a ridge away, maybe two. I'd say a half mile away I could easily see what it was.
Before that it was just a small, moving object with weird reflections.
After viewing of the first video (the one at night) I didn't think the object was all that large. And it looked like brown paper. Maybe the same concept, only with paper and initially lifted like a paper-bag hot air balloon (which are responsible for ever-so-many reports of strange floating objects - SFO's).
