Yeah, I don't think Ivan (unless it turns dead north) will really hit much of Florida. Last I saw, it was south of Cuba heading up. But I know - somewhat - those hurricanes can do. My family and I had two come close to us when we lived in Tampa. They had seriously downgraded themselves when they hit us (high catagory tropical storms - catagory 1 hurricanes) so I can't say I've survived anything close to what you guys are going through.
What I find funny is how people know its the Sunshine state yet they don't know its the Lightning Capital of the World. On top of those hurricanes we had many tornados zip through our county, innumerable flash floods (we would regularly watch people canoe and raft down major intersections of Tampa), and everything in between including 100% humidity 90 degree days with a broken air conditioner. I'm satisfied with just tornadoes and rain up here (and snow - nothing like having a snow day

).
One funny story about the heat though. I was at a Boy Scout camp once and it got to 115 (without the heat index) with easily 100% humidity. They closed every workshop and event down except for the lake (obviously). So there were about 300 of us in a decent sized lake - but it was known to have an alligator or two! Let me tell you that no alligator stopped us from cooling off, except for that one kid used to ride broncos and thought it would be fun...
Stay safe (and dry)
