try searching the torrent sites, i dont think theres a website you,ll get it off...torrent,newsgroups or maybe a forum somewhere..
but if she freting over driving in florida she dont need to worry its easier than driving over here, road are big and well sign posted, ive been three times and again in three weeks and ive never been lost once.
they seem to know how to drive over there, you get no speeding knobheads like over here in there boy racer cars lol.
but if you really need the maps try the above for searches.
