I did a quick search on their web site and did not find anything in regards to general admission. However the following was under the Entertainment section.
The following items are NOT PERMITTED in the Events Center or Budweiser Grandstand Arena
Outside food or drinks (Venue has many individual concession stands)
Laser pointers (Will be confiscated & patron subject to ejection).
Recording devices (Audio, Video, or Cameras as restricted by show)
Weapons or items construed as weapons (e.g., guns, knives, sticks, fireworks)
