James,
Very nice video, smooth flying made it enjoyable to watch.
I was curious about flying there because I'll be driving through there next month on the way to Couer d'Alene. I looked up the Falls in the B4Ufly app and it shows the falls in the circle of several airport and heliport zones. A while back I was reading there are some restrictions around "power stations", too. Any concerns about restrictions being enforced at the falls?
