I don't think the drinking policy inside the stadium will change.
What they (the city and Boise State ) are looking at is the current drinking restrictions around the university and the greenbelt and want to make it more uniform and enjoyable for those tailgating.
I heard the new parks and rec director was a little 'surprised' at the current policies. How members of the same tailgating group could be legally drinking alcohol on one side of a sidewalk while other members of the same group could be breaking the law by drinking on the other side of the sidewalk.
Hope they get it straightened out.
