La Croix makes a Pamplemousse-flavor sparkling water, that says "grapefruit" on the can only in a small parenthetical. You can get it in Lawrence, KS, and in Chicago, IL, but, grievously, not in Lincoln, NE. It is the deliciousest La Croix flavor of them all!
This of course refers to the well-known Running of the Citrus when wild grapefruit charge through the streets of Pamplona each summer. Unfortunately several British tourists are trampled into mousse every year.
