well, first of all, unless you live in utah where there's no bars, what's the point of having a flask on you so it gets all warm. In addition, they barely carry anything so unless you have the tolerance of a puppy, I still don't see the point. I always thought of it as a little hipster trend to try and look bad ass yet old school.
I'm sure all of you benefit from it, but in a place like Montreal where liquor is slightly less accessible as water, carrying around a flask is kind of strange to me. Isn't it annoying having one around too?
