Talking about getting lucky while shed hunting, I did.  I was walking a small drainage in early March behind my home in southern Decatur county Iowa and stumbled upon this heap of horns.  I could see it from 40 yds away,  jumped the ditch and climbed up the grade to the skull,  no shrinkage here, it got bigger as I completely pulled it out of the brush pile.

The weird thing was that I walked this same drainage last year and didn't see the horns.  It appears the skull/horns are two years old.  Put a tape on it at 174 as is, it has a couple of rodent damage spots and a couple of broken tines, otherwise with a full rack it would easily be in high 180's. 

Last year I also found a dead monster buck, I have mounted this one, as I am going to do with the current one.  Check 'em out.
