Gary Sizer was born in New Castle, Pa. Years of military service and software consulting fed his passion for travel, which he chronicles in his latest book, Home is Forward. After walking the Appalachian Trail in 2014, his before and after pictures went viral, and since then millions of people have seen him in his underpants. Now Gary hikes and lives in the hills near Asheville, N.C., where he occasionally records stories for NPR's The Moth.
