When I was a child, we drank seltzer. I discovered however, that most everyone else called it either club soda or sparkling water. I finally realized that it ust be a regional thing. And, although I was born and raised in Los Angeles, my dad is from Philly and I must ave picked up 'seltzer' from him. So now I'm wondering, where are you and what do you call it? Seltzer? Club soda? Sparkling water?
