I was working in Montana for 2 and a half months. I would often take road trips on my days off. I was on my way back to Great Falls from Billings when I saw this storm cell building. I knew I needed to fly the drone. I used my Mavic Pro with my PolarPro ND16/PL (probably my favorite filter). Preprogrammed waypoints with 2 second intervals. Then I played around with it a little in Adobe Premiere.
