No nightmares! I made one Antarctic patrol stocked with a Public Library's rather rare tome on Polar exploration. Imagine their chagrin recieving a reply to their 4 month overdue notice postmarked Little America ! The very idea of launching a small boat in those waters and shooting the sun ( sun, what sun Chief?) inspired my own efforts at seamanship and navigation. That was a REAL classroom! The voyages of Captain Bligh and the wreck of the Essex ( inspiration for Moby Dick and also subject to an upcoming TV special) led me to Motorlifeboat duty.
