 A measure that would ban cruise ships with 250 or more passengers from docking in Juneau on Saturdays qualified for the October 1st municipal ballot, setting the stage for a debate about how much tourism is too much in a city that's experiencing firsthand the impacts of climate change. The measure would also ban ships on July 4th, the day when locals flock to a downtown parade. The Ship Free Saturdays initiative that qualified this week goes to voters unless a local assembly enacts a similar measure by August 15th, which is seen as unlikely.
