Dr. Dan, for route and timing consideration of the Florida leg:
Jacksonville is at the intersection of I-10 and I-95. You're welcome to stay here. Depending on when you come, the Amelia (Concours) is the 3rd weekend in March, the Blues Festival is in April, the Jazz Festival is in May, the Main Street Cruise-in is every 4th Saturday, the beaches are year 'round, I can arrange canoe or kayak tours of the Okeefenokee, or St. Johns River and the world's largest outdoor cocktail party is in October (FL-GA football). We're 40 minutes from the Castillo at St. Augustine, 90 minutes from Daytona International Speedway.
