Black chemtrail? Wierd visual phenomenon? (not prospecting related video)

As title says, I was driving down the freeway and noticed some really wierd phenomenon in the sky, so i decided to film it.... Ignore the rambling ! (also holy shit the video quality is completely trash... apologies. i don't think i can change that now... It's super clear on my end... If you watch the video really zoomed out you can better see it. It's in and intersects under the cloud to the middle left of the picture...) And for those of you who come for the prospecting, i want to do a huge apology. I have simply been lazy. That and my video making program i was using grenaded on me so i lost footage and was unable to make any more videos on it... Now i have to go buy new video making software, learn how to work it, and then we can be back to "normal" .... To be fair though, I had not had the greatest days on the river recently either... Sub grammer days for the most part... Recently discovered a new chunk of the river though and maybe i can make a couple videos there... No promises! But yeah i definitely feel bad for abandoning you without any videos for this long !
