re: Nike sites
Any in your backyard?
Used to be, until I changed locations...
When I was a Cub Scout, they were still active, and my pack got the nickel tour one Saturday. That was outside of Chicago.
Outside of Philly (PH-07), I could show you one that has been converted to a library surrounded by municipal park... and the radar towers forPH-15.
Along the south-central New Jersey coast, the forward radar towers for PH-23/25 still stand, abandoned concrete cylinders with no clue of their origin for those too young to remember.
