Congrats on a unique trophy. I agree with Mullet, mount that buck on the wall.
I hunted 3 piebalds in WV several years back. I tried to get one with my bow and did get close a couple times. Found all 3 shot by a rifle hunter later in season. I let the word out if I found out who was responsible they would be mine, but I never did find out who shot them.
I guess the only "bad luck" is if you are born a piebald deer, since you sorta stand out from the rest..
