Depending on the State or Country it may be illegal to purchase tickets outside the event in the area around the arena/stadium/parking lot. Plus, there is always a chance that the tickets could be fake and you loose your money. When I need tickets I go to a reliable source. I have found Vertex Tickets to be a great resource in securing upgraded or tickets to sold out events. You can buy online with a 100% guarantee that the tickets are authentic.

The Milwaukee Brewers site is the best site to buy tickets for large groups. This is because it is an authentic site and you're less likely to get scammed. Group tickets must be purchased with a minimum of 25 plus people attending a game.

Glad you asked! So, you want to know if your ticket is authentic, eh? Well, what you need to do is look at the bottom of the ticket while running the ticket under cold water. If you did this correctly, it should open a secret panal on the ticket. In that panal is a blue square. What you need to do now is take a lighter and place the flame on the blue square. If your ticket is authentic, the square will turn purple when tuoched with the flame. If it doesn't do this, your ticket is not authentic. Hope this helps!
