Was looking up hurricane related things on here, and came across a thread about the rumored Baxter, Mn Hurricane 130, so i began my Google guest and somehow ended up with a page where it gave me info about the sirens in most of the towns in Minnesota. This has some very useful information, I believe this was done in early 2007.
