Garrett Peck is an author, historian and tour guide in the nation's capital. He leads tours through The Smithsonian Associates, and his Temperance Tour of Prohibition-related sites has been featured on C-SPAN Book TV and the History Channel program "Ten Things You Didn't Know About" with punk rock legend Henry Rollins.
