So it's still a little bit hairy as to why Citrus Cooler is back. But I found out a couple more details. Although it's not on the Gatorade.com site, the flavor is available in the southern region of the U.S. --Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, New Mexico, North Carolina, South Carolina, Tennessee and Texas. It's mostly in the new 64-ounce bottles, but there are some 32-ouncers. Citrus Cooler can be found at the following supermarkets: BiLo, Brookshire Brothers, Bruno's, Food Lion, Kash N Karry, Harris Teeter, Ingles, Kmart, Kroger, Publix and Winn-Dixie. You can also get Citrus Cooler in a Xtremo vending pack, which includes eight bottles of Mango, eight bottles of Tropical Intenso and eight bottles of Citrus Cooler. I'm not sure why this is a regional thing. It's not like only the southern region of the country can appreciate it.
