What's it like to be both blind and gay? How does romance work for those who, despite this double disorientation from the mainstream, are certain of their sexual identity? To find out, Michael Lowenthal signs up for the Rainbow Bear Valentine's Cruise and joins a group of blind gay men, along with their human and canine companions, for a weeklong Mexican sail on the Royal Caribbean Vision of the Seas. The result is an absorbing travelogue - by turns playful and poignant - that gives Lowenthal the chance to reflect, not just on desire, disability, and the power of the visual, but also on the mysteries at the heart of all attraction: How do any of us sense what we might end up wanting? How do we truly know whom we love?
