Great story Justin, and I for one want you to keep posting up about your good ol' dad.
I never get tired of hearing father and son hunting trips, memories,. and thoughts.
I think it is an awesome way to honor him, and I'm sure he would be proud of what you are going to do with those tags, one way or anther!
Sorry for the loss of your Father. I lost mine a lifetime ago and would give anything to sit down and talk with him for just five more minutes and say four words to him.
There is no reasonable explaination for the behavior of the antelope you harvested. I will attribute it to forces not of our making. Enjoy your time hunting and think of your Father often.
