JOHOR BARU: Every Wednesday, a 66-year-old man spends an hour riding his old motorcycle across the Causeway just so he can see his son, who is in a Singapore jail, for about 15 minutes.

This has been his routine for almost 10 years.

The night before, Cheong Kah Pin, who is a pasar malam trader, wraps up his business to head home and rest for a few hours before beginning his journey at around 2am.
