Wisconsin volleyball (of all things!) is kind of like this. Season ticket holders get assigned seats in the center sideline sections and the rest of the Field House is general admission seating. A few years ago, UW started putting bumpersticker labels on the season ticket seats, with the names of the ticket holders. But we still regularly (though not every time) find people with general admission seats wandering into our section. DO YOU NOT SEE THE NAMES ON THE SEATS? Having said all this...if we didn't already have two 20-packs in locations we really like, I'd totally consider one of these $30/month things. That way if a specific night is super humid/stormy/otherwise yucky conditions that won't postpone the game, but will make driving or sitting through it a pain, I wouldn't feel like we were out $50-$70 per pair of tickets missed. I'd just wait for the next game. The ticketing section of the Brewers' website allows you to view the seat map*, so you could theoretically find unsold seats (barring the possibility of a late walkup sale) and feel less likely to be in an awkward spot with other fans or an usher. Since you need the Ballpark app to make this ticket deal work, you could also upgrade your seat more legitimately (as needed). *Though the seat map uses Flash, so it can't be viewed on an Apple mobile device.
