Is sparkling water easy to find in convenience stores, gas stations, etc. where you live? I live in the midwest. We have no problems finding it (warm) in the grocery stores, but never see it in the coolers next to the Pepsi, Gatorade, Red Bull and Aquafina. No problems finding it in the largest cities like Chicago, but it's even difficult to find it in many restaurants in cities like Indianapolis, Madison, Cincinnati, etc. I wonder if there will ever be a demand for sparkling water in the US like it is in Europe and the ME. It's by far my 10yo daughter's preferred beverage (we don't drink soda and I think all kids like fizzy drinks). On a recent trip to Chicago, it was nice to be able to pick up a cold bottle (even in glass bottles) whenever she was thirsty rather than her have to drink still water out of plastic and complain about the "plasticy water". Until this recent trip, it really hadn't dawned on me how hard it is to find cold sparkling water where we live (bigger city, but not a metropolis). Thoughts?
