Yeah, odds were not good. It was only for 1 tag, and although I have no idea of the success rate, I know that regular F/IM draw hunters had 50 tags, depredation 100, 150 and 150 that I know of. There may have even been another depredation besides these 3.
So that's at least 450 hunters. Maybe 50% success would be chances of getting the billy tag of 1/225 or less than half of one percent. At best it was maybe 1-2% chance. I knew guys who were pumped to whack a nanny for the chance of the billy tag, but in reality it wasn't any better than the chances of drawing a tag in the regular draw.
And for the record I think G&F is crazy knocking down the population like they are doing.
