We'll leave you with this frankly unsatisfying extract from Boca Raton, a shoddy book in the Images of America series that Sarah picked up at Barnes & Noble:
Anyone who has taken a Spanish class in high school or college probably knows that "boca" means "mouth" and "raton" means "mouse," but contrary to conventional wisdom, Boca Raton does not mean "mouse mouth." A more likely explanation is that it is a term for an inlet, because it serves as the mouth of a waterway, and Boca Raton indeed has an inlet of its own. The term "raton" can also be used to denote a reluctant or cowardly thief. Romantic legends and tall tales spread by early developers suggested that the calm, relatively shallow waters of Lake Boca Raton provided a haven for pirates and mariners hoping to wait out inclement weather.
Indeed, these pirates have waited out the worst of the Canadian winter in these waters. Home!
