Two of the Blue Angels on their Thursday afternoon practice session passed over the Oslo Riverfront Conservation Area (ORCA) as seen from the front of Audubon House. The tall trees surrounding Audubon House preventing any sighting of the Blue Angels unless they were almost directly overhead though the thunderous roar of their engines could be heard all through the woods. The Blue Angels are performing at the Vero Beach Air Show on 21 & 22 April 2018. Naturally, rain is expected over the next couple of days.
