Daniel Echeverria is an Argentine motorcyclist who is obsessed with Arthurian legends. He has created the "Excalibur Bike," a motorcycle decked out like a medieval horse (by way of a Vegas strip hotel) with a fire-breathing dragon on the front. Kingsley, who ran into him in the West Village, sez, "Daniel is on a quest for the legendary Camelot castle (which he firmly believes in). He says it took him 3 years to armor his bike. He has a cart full of promotional materials (like posters etc.), and a collection jar."
