Darrell,
You are between Disney World and Dayton Beach of Interstate 4 about 1 hour in either directions and Cape Kennedy about 2 hours away, great if you are taking the family while you umpire.
Largemouth Black Bass for the catching in the St. John's River and other fresh water lakes nearby. Check this website as it looks like a good host city,
