I was there for just 2 days of a 3 day shoot. The plan was to shoot the Sandhill Crane migration. We worked along the Platte River near Kearney.
I'm afraid that it didn't go that well. The birds were very distant and skittish. Also, the landscape in which they're found is bleak because of the time of year. Great for briders, but not photographers. Bosque del Apache in New mexico is a much better venue for cranes and birds in general because of the lovely surrounding landscape and great south western light. The wirldlife reserve there is also much more amendable to doing photography than the Platte River which only has a few public access points.
We had good light, but all in all nothing special came of it. Lots of frames shot but no "keepers". This sometimes happens when doing wildlife work.
We then drove up to the Sandhill region in the northern part of the state, but found it to not be terribly interesting from a photographic point of view.
After that we headed up to South Dakota and spent an sunset and sunrise in Badlands NP which we really enjoyed, but again which didn't produce any really worthwhile shots.
Of course we shot along the way, driving though a lot of NB and SD countryside. We didn't take any Interstates, instead sticking to the more interesting back roads.
Three shooting days, about 1,500 frames with 3 different cameras (1Ds, Mark II and Pro 1) and nothing of publication quality. This sometimes happens.
As for NB, it looks very much like Ontario, where I live. Mostly flat, some rolling hills, lots of farms.
