Hey, isn't that . . . ?: Billy Baldwin

-- Billy Baldwin touring Mount Vernon Tuesday afternoon -- as chaperone for his son's grade-school class, a group that looked to be roughly 10 or 11-years-old. The actor (No. 3 in the legendary Baldwin brothers lineup) seemed relaxed and pleasant; said it was his second time at George Washington's home. Shorts, blue button-down shirt with a "Billy" name tag.
