In 2004-2005, I was selected to be the urban historian who would help host a new show for the Discovery Channel called "Urban Explorers." It was an absolutely wonderful time filming it, as we were being asked to do what I like to do in my spare time anyway: explore old structures, research them, and talk about them. (And having Discovery Channel behind you really helps in getting access permissions-- check out our visit to the old freight tunnels underneath Chicago in that episode! Getting in to those had long been an ambition of mine.) Unfortunately, as much fun as it was, Discovery only funded us for five episodes. Our time slot was given to the show "Dirty Jobs"-- a cool show in its own right, and maybe it just shows that we didn't get dirty enough when filming our show!
