Check out The Great Lawn during tailgate
To the west of the stadium is "The Great Lawn", which holds tailgating events prior to most games. You cannot park on The Great Lawn, but you can easily walk/roll your stuff to it from the west lots (especially orange). As the name implies, it is a grass field, making it cooler during the hot months. There are usually bands and some vendors selling food and beer, and it tends to have a more family appeal during some events. Bring your ticket; it is often required for entry during larger events.
