Upon closer inspection, I noticed that there is a blue tube running from the back of the pack down the front. I believe that the company who manufactures that pack calls it a "hydration bladder". That is the politically correct term for "booze tube". I mean c'mon, hydration bladder? More like drink it up and empty your bladder

It is a very nice pack and I hope it's not too $$$$$. I wouldn't mind having one for summer bank fishing expeditions. You got those at Kauffman's, Sparkey?
