There is a great public hunting area just west of Ogalalla called the Ogalalla strip. It is between the interstate and the south platte river and from Ogalalla to halfway to Brule. I can't tell you how many acres it is but I guess it is about a mile wide and 2 or 3 miles long. It is full of food plots, Russian Olive trees, and willows. I hunted there a couple of years ago and it was full of deer. It also is a walk in area only but it is worth the time to check out. Good luck
