We recently watched the documentary "Tapped" about the bottled water industry. It was pretty well done and highlights some interesting aspects of the history and problems associated with the product. Anyway, we still buy bottled water; particularly when camping, fishing, and while on road trips. It's just dang convenient being able to grab a cold bottle of water from a cooler much like a soda. We do try and re-use some of the better quality bottles. I've never tried those "hydropack" things, mostly because I like cold water. What's your approach to water while out wade and float fishing?
