Yep, it's Glades County.  Monroe County is strictly a mailing address
these days.

Come now, an imbedded tower may be buckled by high winds but it isn't
going to to be torn loose from an 8000 lb base.

Hey, no fair!  You snipped my one-line comment about being ahead of the
game compared to the above--without inserting SNIP.
It's sarcasm Steve, sarcasm.


Now some questions about the wind ratings.  I'd like to know what they
represent and who compiled them.  Are they the expected highest average
speed, highest expected gust, or what?  And under what conditions?  Are
they under cyclonic conditions or strictly straight line winds. 
Obviously they don't include tornados or most of the country would have
to be in 200 mph+ zone.  Lastly, and this is important, what kind of
miles are those?  Are they statute or nautical miles per hour?

Your turn :-)
