I was quickly set straight by friends on the ground:  South Haven won't work on Friday the 20th as there is a Tall Ship extravaganza under way. 

PocketShip would be lost in the crowd.  So with invaluable input from our agents on the ground, we're shifting camp to Saint Joseph, a few miles south, and we'll drop in at Brian's Marina there.
