refreshing cooler

I love making cocktails, especially grapefruit-based ones, but not convenient to do so when we are at the beach or on our boat. These do quite nicely in those instances. Nice grapefruit flavor. And I love that it's gin-based (gin cocktails are always superior to vodka-based ones in my book). Wish that it was a little less sweet. Could easily cut the sugar down by a 1/3 to 1/4 in my opinion and it would taste even better. As it is I dilute with carbonated water so it's less sweet.
