Tampa eh? I grew up in North Palm Beach and my Dad used to live in Melbourne. He just passed this past September but I have nothing but great memories of Florida and of course him.
In fact I was there during Irma taking care of his funeral. Even though it was a difficult time for some reason hurricanes have always excited me. Must have been all those years waiting for the next one to come when I was a kid as Dad would always take us to the ocean and body surf just before the storm hit. Fun times!
Anyway, Welcome aboard!
