Nebraska always impresses me. They are not front-of-mind when it comes to nature tourism but they continue to develop exciting products for people seeking unique outdoor experiences.
The latest is Sandhills Safari Jeep Tours, a five hour spin to see some unique plant and bird species. Last year people saw the rare bobolink, marbled godwit and great egret. If this sounds like something you'd enjoy, book soon as it the tours are only offered in June.
