First off congrats on a great season, looks like you guys put as much time into scouting as hunting to be that successful!!!!
We have killed a few quills but never one with that much white, that's a dandy for sure, glad to hear you sent it to the taxidermist, bird of a lifetime right there!!!
Here is one we shot last fall...
