Not much of a liquor drinker myself, but used to enjoy a rum and coke on a hot day. Apparently the rum in the drink is Cuban light rum, e.g. Bacardi How about you?
I love rum and coke, but if you add a lime juice to it becomes the Cuba libre. 
Ah, ok. The drink originated in Cuba did it not? Do you add lime juice to yours?
Yes, it was created after Cuba declared independence from Spain and yes its quite good.
I'm afraid if I drank one I'd fall over! But it is popular worldwide. Prefer a single malt myself.
