== Old data, category changes, location limits == 

 I have been using the 90s style interactive NOAA reference site to try to confirm some records, such as Miami Beach's all time low of 32 from the chart on the Miami Beach#Climate page, as well as the notorious and bone chilling figure of 27* F for Miami on February 3, 1917. Turns out the only way I could find that record was going by "Miami area," as record for MIAirport and Miami Beach is unavailable for 1917. This makes the record dubious, especially considering that Miami Beach was incorporated in 1915 and by that point weather records were not all that uncommon. I've added quite a bit to Climate of Miami to make it a little more candid and informative. With several category changes (a recent half step up in USDA plant hardiness zone, and probably a whole step if pre-mid-century could be considered, changes in Koppen, and dubious and varying reporting sites pre-MIA time, it's a wonder if the older data should be discarded. At the very least, referencing is easier to more recent history (though some hard copy of a book of older more lauded history could perhaps be found). A bragging right is Key West's status as the "only city to not have a frost" in the continental US, but Miami Beach's apparent all time record low of 32 is pretty dubious in that regard, either way it is significant. If it was a frost, it should be mentioned to clarify that Miami Beach was considered in this bragging right. If it wasn't, then the bragging right is a lie.
