First Mule Deer down

Went to the sandhills of Nebraska with a friend to hunt Mule deer. Long story short found some on public land. Tried the spot and stalk very hard to pull off. Used to hunting tree stands for whitetails in Missouri. 2nd to last day just got in the bottom where the hills came together with some trails and shot a nice doe at 42 yards double lung went 20 yards fell over. I am hooked on mule deer. Saw some small bucks on the trip. I know NE is not know for trophy Mulies but had to start some were.
