Douglas, you wondered if anyone carries stuff in front. Well besides my home-grown belly I don't really anymore (the biggest weight reduction I could achieve).
I have, however, tried front carry systems long ago. Years back I carried a Dana Designs Wet Rib. When I could get it snugged down so it wouldn't bounce around it worked acceptably well for water and snacks. However, overall I have found that keeping my water in water bottles in side pockets or using a hydration bladder plus keeping the days snacks in the top lid of my backpack is how I prefer to go.
I could imagine situations where I might go with a front pack again, but I'm not in a hurry to try any now mostly because I'm not a big fan of things bouncing on my front even a modest bit (why I don't like a camera hanging off my necks down my front; hanging across my shoulders, like a purse, is bad enough – though I do that often).
