I got an email from a player asking about The Ferry. This was my reply:
"I checked with one of the ex-Panther guys here in Oz, but they confirmed how we played it:
the ferry is needed to move your player counter from one side of the Whangpoo to another.(you pay going and coming back as the transport co card says) - - from either district- its not numbered as the airfield is so you can never land on the ferry."
