Yet Another Trail Photo

Hi, folks!

Here is an interesting photo I snapped above my house (and expanding across my neighbours' houses) with my new digital camera. This was taken at approx. 4:30 in the afternoon a few days ago.

I have a few more photos, but I think this one came out the best. By the way, the little black spec is not anything suspicious. It's a simple bird, haha.

Which kind of trail are you claiming this to be? A contrail, or a chem-trail? As a follow-up question, why do you think it's whatever you think it is?

I'm not claiming it to be anything in particular, haha. I just used the term "trail" because of its obvious shape.

To be honest, I just thought it was fascinating (whether just a normal cloud formation or something else). Nothing more, nothing less. I don't see trails of any sort in the sky where I live very often, so maybe I'm the only one excited by it!

Sorry if there was a misunderstanding!
