A network of numerous concrete and steel bunkers and observation towers were quickly erected across the tiny State of Delaware's coastline in the 1940s in an effort to keep an eye on German U-Boat patrols that were coming into the Atlantic Ocean and into the Delaware Bay approaching Philadelphia to the North during World War II, and to be prepared for the eventuality of a German land invasion.
Many of these structures still exist and have become summer tourists attractions in what are now State Park lands. This photo shows one of those once-vital observation towers surrounded by our first snowfall of 2017. The temps were down to about 19F yesterday late afternoon and the H performed just fine with normal battery life throughout the flight.
