I felt ok when I got up - which was surprising. We started at 07.00 today. Needed to have a quick breakfast before leaving the hotel at 08:00 for a 09.00 fishing trip about an hour away. The speed limits on the way were typically 50 or 60 - still in km/h, but difficult to maintain due to the already heavy weekend traffic on what we decided was a weekend/tourist route. In general, driving anywhere in Okinawa was frustrating slow and, add to that, every second car is a hire car
