Probably good advice above, but:
Bottom of page one of the Big game borchure says:
"License cut off dates: Unliminted licenses are not sold after these dates. You must buy them at DOW offices:"
then it give midnight before the season as the dates for each season
One retailer may "sell Out" of liceses, but that doesn't mean that others are out. Stop at the first Walmart, etc you see when you enter the state and buy one if you choose to wait. We have never had a problem, but then we always get there 2 days before the season opens.
I would definately buy it ahead of time if you plan on getting there late the day before the season.
