I with all the other pirates into the spiced dark rum - Captain Morgan's generally being the spiced rum of choice. Although the best rum I've had so far is Tanduay from the Phillipines. That with some ginger beer, and a squeeze of lemon and lime...Mmmm.
I'm also down with the Mojitos (when mixed right) and, of course, the liquid gold that is Chili's Margarita Presidente. I could drink that until I could drink no more.
