Basically, a list of all the things security is going to take from and most likely never see it again. Totally a “you’ve been warned list!”
Speakers & Audio Equipment
Alcohol & Illicit Substances
The Alcohol policy is typically very strictly enforced (gotta that extra more money). Make sure you are following the acceptable amounts per person and remember no glass.
As for drugs and other substances. You will be searched and they’ll find stuff so just skip that hassle & anxiety by not bringing it.
