Where are you looking at flights? Expedia shows about $100 difference between Green Bay and Milwaukee from LAX.
Are you looking to fly in and fly out the same day? Probably a lot of people flying in and out on game day.
While driving itself is very easy Car hire isn't cheap and would add about $200-300 a day.
Yeah was looking at flying in on the Saturday of a game weekend, and then flying out the next Friday (the day after another game), it's just too much, especially with our exchange rate. Better off leaving it as a fantasy that something that is realistic for me at the moment.
