The roller coaster at Seaward in Orlando, Florida ( if you have kids you'll understand) is called the Stingray. This began as an exercise in using my new GoPro Hero4 and ended as an exercise in editing with iMovie on 10.10.5 I could never use iMovie before. It made no sense to me. But this latest version is really good & set up somewhat like Premiere Pro. The music is by a very talented player named Jeff Stattner.
