From this super-easy-to-follow Fox graphic about "Colby Lewis Travels" — which probably should've been Colby Lewis's Travels, but he has traveled, so whatever — the map indicates he spent a sliver of 2007 in Kansas City, Kansas as a Royals pitcher.
The Royals home address is Kauffman Stadium, One Royal Way, Kansas City, MO 64129.
