[Talk-us] Civil Defense Sirens?

[Jeffrey Ollie]

With the start of Tornado season in the Midwest upon us, I thought it
would be interesting to map civil defense sirens:

However, I can't find any existing examples and either I'm tired or
coming down with something but I can't really think of a good way to
tag these either.  As for rendering, we could use the International
Civil Defense symbol:

Might make a good project of the week too...
