That old church has Change Ringing Bells.
in some sense direct link 5G antennae are like a high tech version of that same concept of 'change ringing' only at a gigahertz range and done directionally.
when I make a meme with effects that does drastic changes to color I always try to mask out the flags to allow for them to still be Red, White, & Blue.
the lamps are not lit. neither is lit.
one lit: land
two lit: water
none lit: earlier in the day before they are lit .
so we do not know.
there were always two lamps. how many would be lit was the key.
