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

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

Might make a good project of the week too...<br><br></blockquote><div>That would be fun. I'm up for making that a "US Project of the Week" if the international folks aren't willing to help :).</div><div>
<br></div><div>Are the rural ones visible from aerial imagery? Perhaps we could start researching which states/areas have active sirens?</div></div><br>
