parking in Henderson Carriage Building lot?

[she-of-emeralds.livejournal.com]

Hi folks,

Does anyone know if it's all right for an out-of-town visitor, just here for the day (Sunday), to park in the parking lot behind the Henderson Carriage Building on Mass. Ave.? This building is the one with the Elephant Walk restaurant and is across a small street from the Hess gas station. The lot appears to be plowed and is generally pretty empty on Sundays. Any information would be helpful. Thanks!
