The Saturday afternoon jam begins at around 11 am and 12 pm onwards right after Endah or Indah Parade Sri Petaling Ampang Bound. I have been enjoying the same jam since 1999 till now 2006, the good old jam, never miss ! You could upgrade the standard jam to super nova extreme jam if there is a heavy rain. Paid RM1.50 x 2 at Kesas, enjoyed 8 minutes of smooth drive and this is the end of smooth drive ok ? This is the end of smooth drive.
