as long as it didn't get to hot before you put it in the freezer your ok.it will keep in the freezer for a few mo's. with no problem.
an idea,have it mounted laying on a limb,and hang it high and you will never notice the lighter back.if you want to see the back,have it mounted coming down a limb.just a couple ideas.
congrats. on the trophy.I have one that is black untill you get close,then it is reeeeeeal dark brown and black mixed.
