Sneaky Shorts and the such?

I've never used any those sorts of things, but vodka is easy to hide.. I had a full pint of vodka plus 2 nips and a 5 hour energy both days of Boston Calling this weekend. It all fit "in my bra"

You're allowed to bring in a full camelbak. If you slide in one of those collapse-able plastic flasks in the pocket along with a full camelbak bladder it blends right in.

This is actually what I'll be doing this year. A little less uncomfortable.

I've always tucked a can or two in my swim trunks (because they have a liner), or tied my drawstring around a pint of vodka and let it dangle.
I'm going all vodka in Centeroo this year, and mix it with the lemonades (refills are only a couple bucks!)

One thing I have noticed, and done a few times, is its easy to simply bring a drink in plain sight in my hand.
They are so focused on searching and patting you down, that they look past the obvious.

Must be a forest for the trees kind of thing.

Dont they check standard camel backs for their contents?

Offensive. I am talking about putting the vodka where the water goes, do they open that compartment at security?

Someone on here recommended putting vodka in one of the spritzer fans instead of water and then pouring it into your drinks from there, I believe I will try that maybe the vodka in the shorts probably a small water bottle.  And the carry a drink in that seems to work also.  

I was asked every time last year. So there you go.
