A shockingly casual trespasser caused some serious damage to the Brewers home ballpark. 

Lots of questions here.

The front door was just open?

No one was in the park?

Are the keys usually left in the vehicles at sports arenas?

Dude just knew how to operate a tractor?

How did he pick what he was going to destroy?

Did he raid a concession stand?

He apparently caused $40,000 worth of damage is being looked for by the Milwaukee police.

Luckily the Brewers are done playing at Miller Park this year so the infield probably was slated to be removed anyway. You wonder what would have happened if they had to host a game over the weekend.
