I am attempting to buy tickets to a Brewers Twins game and when I got to the page it says that you can buy half priced tickets for seniors and kids so I was wondering if anyone knows how young you have to be to be considered a kid and how old you have to be to be considered a senior. The ticket page doesn't say and I can't find the information elsewhere. Also, are the tickets different in anyway or are my kids and dad going to have to show ID to use them?
