Silly Goose,
That is a neat hunt story and pictures!
I would echo the sentiment that wearing some hunter orange would be a really good idea while hunting. Many, many years ago, before Nebraska required wearing orange, a guy I went thru high school with, was sitting on a bale pile watching a creek bottom trail. A guy hunting coyotes came by on the road about 500 yards away. Somehow he convinced himself that it was a coyote on the bale pile. The idiot on the road took a "potshot" at my buddy. Hit and killed him!
I have had deer and elk almost step on me while I was wearing hunter orange so I don't believe it is alarming to ungulates.
