There are not only winter standard tests but also summer standard tests in developing cars. Does it matter if there are no pictures?It does not have to be true or make sense. I needed something and this does the job Just fine.
I definitely wouldn’t try to verify anything with a drone. Last time I was in Alaska, I followed an idiot friend of mine on a hike to top of a mountain just to find out it is near a missile site. To make matters worse I had a beard with a typical Hollywood terrorist look. Next thing I know a Blackhawk is hovering over my head with a dude hanging off it’s side with a gun telling me to bug out. You would not believe how fast a man that is about to crap his pants can get off a mountain. A rumor is just fine. No fact checking is needed.
