Day 3 started with a short bus ride down to the Botanical Gardens. We spent a few hours walk around. Dad spent a while chasing a squirrel with his camera.
We walked down the street to the bus stop and caught a local bus into town. For S$20 (AUD$15) (plus S$10 deposits) tourist can get unlimited travel on the trains and busses in Singapore for 3 days, not a bad deal the trains are clean, quiet and efficient. There is never a reason to run for a train, there will be another one in just a few minutes.
