One of the nice benefits of having luxurious hair is using it for awesome costumes or making beautiful hairstyles. One that's so underrated is sneaking in entire freaking bottles of hooch to wherever you please. So take care of those beautiful locks.
Say you're going to a festival and you have no problem getting your hands dirty. Why don't you go there a few days early and bury a bottle somewhere on future festival grounds? Just, you know, remember where you buried it.

Shows will let you bring in food inside your cooler but not drinks, so how can you get the whole package? One person made a new spot for his booze by cutting out the bottom panel of a cheap cooler. He then put in a few Ziploc bags worth of his favorite beverages.
