I thought that Ely, MN was a good place to drop this bug for 3 reasons. 1. This is part of a multi-cache in which 2 of the stops are WWII Memorials to the people who served from this town. 2. From 1940-45 achieved a national record for sending more men (1600 men into the US Armed Forces, about 1/4 of the town's population), per capita than any other city in the USA. 3. Appropriate to the submarine theme- the mines from NE Minnesota supplied the majority of the iron ore needed for the war effort- including the building of subs.
