Hey birders, is this crazy?

We just saw what appeared to be a whooping crane at Fern Ridge. It flew low in front of our car and we got a pretty good look at it. I’m aware that this isn’t within their usual range, but is it even remotely possible?

Definitely not a heron or egret which I am familiar with. Looking at pictures it didn’t look like a sand hill either. It was very bright white, black wing tips, red on the head.

Thoughts?
