The large screens shows the odds for the races and driver information. As we had no idea how to read this information, and we were interested in placing a bet for fun, we had to ask at the information desk how to do so. Once we learned how to do it, we waited for the next race to decide which boat(s) to pick. Turns out the next race to bet on was race number 5 (out of 12 scheduled). The following picture is of our betting slip (I chose the first line of Boat 3 to win and Boat 4 to place second; Kazumi chose the second line of Boat 3 to win and Boat 6 to place second).
Well, we were half right. Turns out in this race, Boat 3 did end up winning, but neither Boat 4 (placed 5 out of 6) or Boat 6 (placed 4 out of 6) came close to winning.
We finally arrived home at around 4:30 pm after watching 3 races and stopping along the way for a late lunch. Still, we had a fun time and slept well after our long bike ride.
