That's it exactly - in the center left of the photo, you see a road heading out the *back* of the TTC. That road empties on to World Drive. If you continue straight across instead, there's an unmarked (I believe) road. That road takes you right into the CM parking lot for the Lodge, and drops you out just north of the main entrance to the building.
This route is less safe than the CBR walk we've been talking about, as one has to cross World Drive with no signal or any other protection. It was mostly a case of doing it for the sake of doing it, like the friend of mine who years ago took a drive down the VSTOL runway because it wasn't blocked off in those days.
